In a sample study of 642 people, it was found that 514 people have a high school certificate. -Maths 9th

1 Answer

Answer :

(d) 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.
