Question

If one die is rolled, then find the probability of event that the number on the upper face is greater than 6?

Answer 1

Sample space,

S = {1, 2, 3, 4, 5, 6}

∴ n(S) = 6

Let A be the event that the number on the upper face is greater than 6.

Here, the greatest number is 6.

∴ Event A is an impossible event.

∴ A = { }

∴ n(A) = 0

∴ P(A) = `("n"("A"))/("n"("S"))`

∴ P(A) = `0/6` = 0
