Given that:
Total number of people n(S)=642
No. of peoples having high school certificate n(E)=514
P(E)=Probability that the person has a school certificate
∴P(E)=

Answer:
n(S) = 642
Let the probability of selecting a person with high school certificate be A
Therefore n(A) = 540
P(A) = n(A)/n(S) = 540/642 = 90/17
