Best answer

(D) 0.8

The total number of people in sample study, n(S) = 642.

The number of people who have high school certificate, n(E) = 514.

So, the probability that the person selected has a high school certificate

= n(E)/n(S)

= 514/642 

= 0.8

Hence, the probability that the person has a high school certificate is 0.8.
