**i)** Even numbers in outcomes = 2, 4, 6 = 3

∴ Required probability = 4/6 = 2/3

**ii)** Prime numbers = 1, 2, 3, 5 = 4

∴ Required probability = 4/6 = 2/3

**iii)** Getting ‘7’ on top = 0

∴ This is impossible event.

**iv)** Sum of the factors of that number is twice to that numbers = 6

∴ Required probability = 1/6
