Question

37% of women consider themselves professional baseball fans. You randomly select 6 women and ask each if she considers himself a professional baseball fan. Find the probability that the number who consider themselves baseball fans is at least three.

Answer 1

Solution :

= P(X=3)+ P(X=4) + P(X=5) + P(X=6)

Now,

= P(X=3)+ P(X=4) + P(X=5) + P(X=6)

= 0.2533126 + 0.1115782 + 0.0262120 + 0.0025657

   = 0.3936685

= 0.394
