Solution


Q.

What is the probability that a number selected randomly from the numbers 1, 2, 3, …, 15 is a multiple of 4

1 4/15  
2 6/15  
3 3/15  
4 5/15  

Ans.

(3)

Given numbers are 1, 2, 3, …, 15.

∴ The number of possible outcomes = 15

The outcomes favourable to event E ‘getting a multiple of 4’ are 4, 8, 12.

∴ Number of favourable outcomes of event E = 3

∴ Probability that a number selected randomly is a multiple of 4 = 3/15
