Answer 1

Step-by-step explanation:

A box contains 20 cards.

S = {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20}

n(S) = 20

(i) Let A be the event of getting multiple of 10.

A = {10,20}

n(A) = 2

P(A) = n(A)/n(S)

= 2/20

= 1/10

(ii) Let B be the event of getting an even number.

B = {2,4,6,8,10,12,14,16,18,20}

n(B) = 10

P(B) = n(B)/n(S)

= 10/20

= 1/2

This is your answer.

I know that helps you very much.
