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 (1)= highlight_green(2C1)(p^x)(q)^(n-x) }}} {{{2(.7*.3)}}}= .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
