(iii)Let E be the event of getting a number greater than 5.

Outcomes favourable to E is 6.

Number of favourable outcomes = 1

P(E) = 1/6

Hence the probability of getting a number greater than 5 is 1/6.

(iv) Let E be the event of getting a prime number .

Outcomes favourable to E is 2,3,5.

Number of favourable outcomes = 3

P(E) = 3/6 = 1/2

Hence the probability of getting a prime number is 1/2.
