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