The probability that a number selected at random from the numbers 1,2,3, …, 15 is a multiple of 4, is

Given set of numbers are: 1, 2, 3, …, 15.


Let E be the event of selecting a multiple of 4.


Outcomes favourable to E are: 4, 8, 12


The number of outcomes favourable are 3.


We know that probability of an event E, P (E)


⇒ P (multiples of 4) = 3/15 = 1/5


∴ The probability that a random number selected is a multiple of 4 is 1/5.
