1. Answer: the probability that a randomly selected dropout is white is 0.4902%

Step-by-step explanation:

According to the provided information,

8.6% of high school dropouts are in the age bracket of 16 to 17 years old.

Then 5.7% of the high school dropouts that are 16 to 17 years old are whites.

Therefore, the probability that a randomly selected dropout is white =

5.7% of 8.6% = 0.4902%.

For clarity sake, we can assume that there are 3000 students in the high school.

8.6% are dropouts :

8.6/100 × 3000 = 258 total dropouts.

Now, suppose 5.7% of the total dropouts in that school are whites, therefore the number of white dropouts in the school is:

5.7/100 × 258

= 14 white dropouts.

We can also achieve this by multiplying the two percentages by the total number of students in the school

i.e 8.6% × 5.7% × 3000

= 14 whites dropouts

This affirms that the probability that a randomly selected dropout is white =

5.7% × 8.6% = 0.4902%
