Question 1130144: I have a question about part b).
A goalkeeper catches 30% of all penalty kicks against his team.
a) What is the probability that out of 5 penalty kicks he catches 2?
***For this I found a solution of 0.3087.***
b) What is the probabiity that out of 5 penalty kicks he catches at least 2?
***I cannot figure out how to solve this. I feel like it's probably easy, but the at least part is throwing me off I think.
Thank you!

Question 1130277: Regarding the Milton Permanent Income Hypothesis
Friedman, calculate permanent income, transitory income, consumption, and saving for t = (1, 2, 3 and 4). Take into account that:
𝑌1 = 2000 + 200
𝑌2 = 2100
𝑌3 = 2200
𝑌4 = 2300
𝐶𝑡 = α𝑌𝑡𝑃
β = 0.2
α = 0.8
Observation:
the "t" in the "ct" is in the denominator of the "y" and the "p" is in the exponent.

Question 1130292: Suppose a study of the faculty at U.S. medical schools revealed that 38% of the faculty were women and 62% were men. Of the female faculty, 32% were full/associate professors, 47% were assistant professors, and 21% were instructors. Of the male faculty, 52% were full/associate professors, 38% were assistant professors, and 10% were instructors. If a faculty member at a U.S. medical school selected at random held the rank of full/associate professor, what is the probability that the faculty member was female? (Round your answer to two decimal places.)
