4.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
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?
16.Hi, I have one question on my math homework that I can't seem to figure out. Please help me! Here
is Imagine that in the voting for a certain award, 7 points are awarded for first place, 4 points for second, 3 points for third, 2 points for fourth, and 1 point for fifth. Suppose there were five candidates (A, B, C, D, and E) and 47 voters. When the points were tallied, A had 155 points, B had 173 points, C had 170 points, and D had 154 points. Find how many points E had and give the ranking of the candidates. (Hint: Each of the 47 ballots hands out a fixed number of points. Figure out how many, and take it from there.)
