Question 862596: us news and world reports ranking of Americas best graduate schools of business showed Harvard and Standford in a tie for first place. In addition, 7 of the top 10 graduate schools of business showed strudents with an average undergraduate gpa of 3.5 of higher. suppose that we randomly select 2 of the top 10 graduate schools of business.
A- what is the probability that exactly one school has students with an average undergraduate gpa of 3.5 or higher?
B- what is the probability that both schools have students with an average undergraduate gpa of 3.5 of higher?
C- what is the probability that neither school has students with an average undergraduate gpa of 3.5 or higher?

Hi

randomly select 2 of the top 10 graduate schools of business.

p( > 3.5gpa) = .7,  n = 2

2 chosen

A- P( exactly one school has students with an average undergraduate gpa > 3.5) 

= P+%281%29=+highlight_green%282C1%29%28p%5Ex%29%28q%29%5E%28n-x%29+ 2%28.7%2A.3%29= .42

 B- P( exactly both school have students with an average undergraduate gpa > 3.5) = .7*.7 = .49

 C- P( neither school has students with an average undergraduate gpa > 3.5) =  1 - .49= .51
