Question

Sue chooses a dress to wear when she goes out with her parents, but she can wear it only if her parents approve. The probability that Sue selects a black dress is 40%. The probability that Sue's parents approve when she chooses a black dress is 30%. What is the probability that Sue chooses ablack dress and her parents approve?

Answer 1

To find the probability, we can mutiply the probability of Sue choosing a black dress(40%) by the probability their parents will approve(30%).

The probability would be:
40%×30%
=0.4×0.3
=0.12
=12%

Therefore the probability that Sue chooses ablack dress and her parents approve is 12%.

Hope it helps!
