13.Hello, I have a problem calculating probability for a certain thing that happened. I'll try and make it sound like
...
it sound like a math problem.
The problem :
What are the chances of a 4 sided die landing on 1 twice and on 2 twice out of 4 rolls. The solution I came up with originally was (2/4) x (2/4) x (2/4) x (2/4) . Which I realized was wrong as this allowed the die to land on 1 four times in a row. So then I came up with this soultion (which i still think is wrong) (2/4) x (2/4) x (1/4) x (1/4) . So the reasoning behind this is : The first roll obviously has a 50% chance to roll on either 1 or 2. Second roll is the same. BUT, lets say both of them land on 1, and now it HAS to land on 2 the remaining two times. So my problem is with the current solution that I have is what if the die lands on 1 on the first roll, then on two for the second one. then the third roll would still have a 2/4 AKA a 50% chance of landing on either one. I'm sure the last roll is 1/4 but I just dont know if the order matters on the rolls. This has been driving me crazy the last hour. Please help if you can thanks

22.Hello
I am a father of two children, one in the IB DP now, and the other is in 9th grade.
...
oking for an online math and SAT/ACT tutor, possibly an IB Math tutor as well.
My children are native English speakers, but go to an international school. They are looking to attend an English speaking school for the university.
Can you please let me know the price range I am expected to pay per hour? Also, I haven’t had some of the best experiences in the past with someone claiming that they could help with SAT only to find out that they weren’t qualified. At this point, I will need a way to demonstrate your expertise as an SAT or ACT tutor. Also, for IB Math, if you are able to do both.
I look forward to hearing from you. Just to let you know, I have other friends looking for a similar tutor. Please make sure to send your CV, and a personal statement if you have one, so I can better understand your teaching/tutoring philosophy better.
Oh yes, where are you located for time zone differences?
Best,
Edward Rochman

Good evening Joseph,
Your forum post this week sparked my interest because of your two debatable topics. Your week 5 topic of "Should churches be taxed or exempted", will be an interesting read. As a person who grew up in the church and seeing what it offers, I am for churches being tax exempt. The money saved from taxes in the end helps the community.
Your second debatable really stuck a cord with me. I hate how reliant we as a society we have become on our cell phones. I use mine a lot, but have being trying for a few months now to be less reliant on it. Kids are at school to learn, not be on their cell phones. The teachers should be teaching and paying attention to the students and not on their cell phones. I am curious, when you say banned, so you mean not even on school property, or just not allowed to be used during school hours? My 13 year old son takes his cell phone to school in his back pack, but we have talked to him about when he can use it. It's mainly for after school activities, so he can let us know when he needs to be picked up.
I look forward reading your papers.

27.My P.O. violated me because I got a DUI (which I completely agree that she did the right thing there).
...
). When she gave me a UA she said I had failed it for methamphetamine (there was a very faint line on the instant test, which means she should’ve counted that a negative for meth result. I have been sober from methamphetamine for more than a year. I would admit if I relapsed, especially since I already knew I was going to get violated for the DUI. She said she sent in my UA and 3 days later got the results back and they were positive (I have not seen the “results”). Is there somewhere I can find scientific proof that these drug tests, especially the instant panel tests, are not fool proof? Especially since I am prescribed non-time release Adderall, Wellbutrin, and gabapentin. That there is also plenty of other things that can interfere/mess with these tests? Can you please recommend any text books, websites, and/or science journals that would help me prove this?

31.I have a paper that is already too long depending on formatting (2 pages max), but I think I haven't
...
addressed everything I'm required to, so I need help condensing what I have and deciding whether there are key parts missing that I will need to add.
I don't exactly need help writing, but help shortening what I've written and deciding whether or not to write more.
I think the first step to getting this done is looking at the writing prompt and my essay and confirming which things I have already addressed sufficiently and which things are missing or incomplete.
Level of detail/clarity, flow, and transitions would probably be the second step. "Level of detail" is where I can hopefully shorten some parts while still sufficiently addressing what I need to.
But if you think a different approach or order is good, please let me know.

32.Hi! I need help with my Netlogo homework, where I need to have turtles create an image of a tree.
...
sically, Tree 1 is just a vertical line, Tree 2 is that line plus two branches, Tree 3 is Tree 2 but with two additional branches on each of the original ones, and so on. Please help! I don't understand how recursions are supposed to be used with this and how to call a previous tree function. Below are additional instructions my teacher gave me.
draw-tree3 [ levels blen bangle]
levels : number of levels
blen : length of each branch
bangle : angle of the branches
The branch length should decrease as the function calls itself. This does NOT mean you decrease a variable, it means that just like fib(n-1) or fib(n-2) you decrease the parameter as you pass it to the next copy.
----Your slider is the STARTING value, the parameter can be changed every time your function is called.
Have the branch decay by multiplying by 0.85 before passing it to the next recursive call.
-When this works, try making the branch decay a slider from 0.1 to 0.9 in increments of 0.01
