if a graduate went on to college full time, there was a 23% chance that they would work at the same time. If a graduate attended college part time, there was a 79% chance that they would work at the same time. If a high school graduate didn't go on to college, there was a 93% chance that they would work. At the time of the survey, 66% of high school graduates attended college full time and 20% of high school graduates attended college part time. If a randomly selected high school graduate worked, what is the probability that they attended college full time? Enter your answer in decimal form and round to four decimal places if necessary. You may want to look at pages 42 through 45 in the notes (videos 30 through 32).
If a randomly selected high school graduate worked, probability that they attended college full time =
conducted by Gallup Inc. asked the following question:
In general, how much trust and confidence to you have in the mass media - such as newspapers, TV, and radio - when it comes to reporting the news fully, accurately, and fairly? A great deal, a fair amount, not very much, or non at all?
53% of respondents has a negative view of the media, meaning they responded with either not very much or non at all.
Two people are randomly chosen, each is asked the poll question above. What is the probability
Part (a) that both have a negative view of mass media? 0.53^2
Part (b) neither have a negative view of the mass media? 0.47^2
Part (c) at least one of the two has a negative view towards the media? .53 (<- wrong)
I have an exam tomorrow and really need help.
The chapters are as follows
1) Discrete Probability Distributions
2) Binomial Distributions
3) Normal Probability Distributions
4) The Central Limit Theorem
These are the chapters. Please I need help asap! Whoever is good at these chapters please contact me Thank you
and how to solve:
“A history lecture hall class has 15 students. There is a 15% absentee rate per class meeting. Find the probability that exactly one student will be absent from class.”
I already know that:
n = 15
p = 15%
q = 1 - 15 = 1 - 0.15 = 0.85
...and then you do: p (x = 1) = C 15 & 1 and then...
Please help me understand the rest. Thank you!
