Answer 1

Solution :-

First we find all possible chances to select the quiz competition.

n(S) = (1,1) , (1,2) , (1,3) , (1,4) , (1,5) , (2,2) , (2,3) , (2,4) , (2,5) , (3,3) , (3,4) , (3,5) (4,4) , (4,5) , (5,1) , (5,2) , (5,3) , (5,4) , (5,5)

n(s) = 19

n(A) = (1,2)

Hence,

n(A) = 1

→ Probability = n(A) / n(S)

→ Probability = 1/19

Hence, probability is 1/19.
