A committee of 5 will be chosen from a group of 4 men and 6 women. What is the probability that at least 3 men are chosen?
Total number of people = (6+4) = 10
Number of men = 4
Number of women = 6
Number of members in committee = 5
number of ways of selecting 5 people out of 10 people = 10C5
number of ways of selecting 3 men out of 4 men = 4C3
number of ways of selecting 2 women out of 6 women = 6C2
number of ways of selecting 4 men out of 4 men = 4C4
number of ways of selecting 1 women out of 6 women = 6C1
P(atleast 3 men are chosen) = P(3 men , 2 women) + P(4 men + 1 women)
= ((4C3 6C2) + (4C4 6C1)) 10C5
= (60 + 6 ) 252
= 0.2619
