The correct option is D 1
Six is the greatest number on a dice.
Let's calculate the probability of getting a number more than six on a dice.
P(N>6) = 0. As numbers greater than six can never appear on the dice.
∴ The probability of not getting a number more than six on a dice, P(N≤6) = 1-P(N>6) = 1-0 =1.
