Question

48​% of men consider themselves professional baseball fans. you randomly select 10 men and ask each if he considers himself a professional baseball fan. find the probability that the number who consider themselves baseball fans is​ (a) exactly​ five, (b) at least​ six, and​ (c) less than four.

Answer 1

If 48% consider themselves professional fans, you'll just have to apply this percentage to the number of selected men to find the answer:

(48 * 10) / 100 = number of professional baseball fans.

480 / 100 = number of professional baseball fans.

4.8

4.8 is not exactly five (a = incorrect)

4.8 is at least 6 (b = correct)

4.8 is not less than four (c = incorrect)
