Answer 1

Answer #1

P( A) = 2/5

P(B) = 2/5

P( A or B) = 3/5

P(A and B) = P(A) + P(B) - P( A or B)

= (2/5) + (2/5) - (3/5)

= 1/5

(5.20) A selective college would like to have an entering class of 1200 students. Because not all students who are o↵ered admission accept, the college admits more than 1200 students. Past experience shows that about 70% of the students admitted will accept. The college decides to admit 1500 students. Assuming that students make their decisions independently, the number who accept has the B(1500, 0.7) distribution. If this number is less than 1200, the college will admit students from the waiting...
