Solution

The correct option is D 12
Even numbers on the dice are : 2, 4 and 6.
Favorable outcomes(total no. of even numbers) = 3
Probability P(E) = Number of outcomes favorable to ENumber of all possible outcomes of the experiment

Let E be the event of getting an even number =36=12
Event F, (Probability of not getting an even number) is the complement event of E.(Sum of probabilites of two complements events is always 1.)

P(F) or P(complement event of E) =112=12
