The correct option is C Probability that a multiple of 6 is an even number.
The probability of a certain event is 1.
So, in case of certain event,
P(E)=No. of favourable outcomesNo. of total possible outcomes=1
⇒No. of favourable outcomes = No. of possible outcomes
All the multiples of 6 are divisible by 2. Thus, all the multiples of 6 are even numbers.
Hence, the probability that a multiple of 6 is an even number is 1.
