Question

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

• A. $\frac{4}{15}$
• B. $\frac{2}{15}$
• C. $\frac{1}{5}$
• D. $\frac{1}{3}$

Answer 1

The correct option is C $\frac{1}{5}$

Multiples of 4 between 1 to 15 is: $4,8,12.$
Number of favourable out comes $=3$
Total number of possibilities $=15.$

Probability that a number selected at random from the numbers is a multiple of 4 $=$ $\frac{3}{15}=\frac{1}{5}$
