A study found that the probability that a married woman is in the labor force is 0.6.Five married women are randomly selected. Find the probability that exactly 3 of the 5 married women are in the labor force.

Solution:

P(x=3)=C(5,3)*0.6^3*0.4^2 = 0.3456

So the probability that exactly 3 of the 5 married women are in the labor force is 0.3456
