Question

When a number is selected from a set of natural numbers the probability of getting a number which is a multiple of 1 is

• A. $1$
• B. $1/3$
• C. $1/2$
• D. $0$

Answer 1

The correct option is A $1$

All natural numbers are also multiples of $1$.
So, probability of getting a number which is a multiple of $1$ is $=\frac{Numberoffavourableoutcomes}{Totalnumberofoutcomes}=\frac{allnaturalnumbers}{allnaturalnumbers}=1$
