It is reported that 72% of working women use computers at work. Choose three women at random, and find the probability that all three women use a computer in their jobs.

Correct answer:

p =  0.3732

Step-by-step explanation:

q=72%=10072=0.72  C3(3)=(33)=3!(33)!3!=11=1  p=(33) q3 (1q)33=1 0.723 (10.72)330.3732   Verifying Solution:   p2=q3=0.7230.3732
