Answer 1

Answer:

ANSWER

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)=  

n(S)

n(E)

​  

=  

642

514

​  

=0.8006

Hence, D is the correct option.Explanation:

Answer 2

Answer:

Let 'E ' the probability that to getting the person has a high school certificate is

P(E ) = n(E ) / n(s)

= P(E ) = 512 / 640 = 4/5
