A hair stylist knows that 87 percent of her customers get a haircut and 40 percent get their hair colored on a regular basis. Of the customers who get their hair cut, 24 percent also get their hair colored. What is the probability that a randomly selected customer gets their hair cut and colored?

The probability a customer gets both services is the probability of getting a haircut multiplied by the probability of getting hair coloring among customers who get haircuts: 0.87 × 0.24 = 0.2088. Rounded to the nearest hundredth, this is 0.21, choice A.
