Solution

Total number of outcomes = 15.

Out of the given numbers, multiples of 4 are 4, 8 and 12.

Numbers of favourable outcomes = 3.

∴ P(getting a multiple of 4) = `("Number of favourable outcomes")/"Number of all possible outcomes"`

`= 3/15 = 1/5`

Thus, the probability that a number selected is a multiple of 4 is `1/5`.

Hence, the correct answer is option (c).
