Question 1133549: 58% 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 by Boreal(15235) (Show Source):
You can put this solution on YOUR website! exactly 5 is 10C5(0.58^5)*0.42^5=0.2162
4 would be 10C4(0.58^4)(0.42^6)=0.1304
3 would be 0.0540 done the same way
2 would be 0.0147
1 would be 0.0021
0 would be 0.0002
At least six is 1-5 and fewer or 1-0.4176 or 0.5824
Fewer than four includes 0-3 and probability is 0.0710
