Question

There are $10$ balls numbered from $1$ to $10$ in a box. If one of them is selected at random, what is the probability that the number printed on the ball would be an odd number greater than $4$?

• A. $0.50$
• B. $0.40$
• C. $0.60$
• D. $0.30$

Answer 1

The correct option is D $0.30$

Given: Total number of balls, $n\left(S\right)=10$

To find: the probability that the number printed on the ball would be an odd number greater than $4$

Sol: Odd numbers greater than $4$ from $1$ to $10$ are $5,7,9$, $n\left(E\right)=3$

Hence, the probability that the number printed on the ball would be an odd number greater than $4$ $=\frac{3}{10}=0.30$
