According to a recent study, 9.3% of high school dropouts are 16- to 17-year-olds. In addition, 6.4% of high school dropou

Answer:

0.688 or 68.8%

Step-by-step explanation:

Percentage of high school dropouts = P(D) = 9.3% = 0.093

Percentage of high school dropouts who are white = $P(D \cap W)$ = 6.4% = 0.064

We need to find the probability that a randomly selected dropout is white, given that he or she is 16 to 17 years old. This is conditional probability which can be expressed as: P(W | D)

Using the formula of conditional probability, we ca write:

$P(W | D)=\frac{P(W \cap D)}{P(D)}$

Using the values, we get:

P( W | D) = $\frac{0.064}{0.093} = 0.688$

Therefore, the probability that a randomly selected dropout is white, given that he or she is 16 to 17 years old is 0.688 or 68.8%
