Bionomial Probability Distributions

#1

51% 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

(a) P(5) = 10C5 •(0.51)^5 • (0.49)^10-5







I tried putting this into the calculator but it was wrong. I know that 10 is the number of trials and 51% is p. I looked at a couple of examples online but I'm still a little lost. I set up the equation/problem above but how do you go about solving it?
