Question

A bag contains 3 red, 4 white and 5 black balls, what is the probability of getting one black ball. 5/12 03/12 1/12 O 4/12

Answer 1

Answer:

A. 5/12

Explanation:

The number of red balls = 3

The number of white balls = 4

The number of black balls = 5

$\begin{gathered} \text{Total}=3+4+5 \\ =12 \end{gathered}$

Therefore, the probability of getting one black ball will be:

$\begin{gathered} P(\text{one black ball)=}\frac{\text{Number of black balls}}{\text{Total number of balls}} \\ =\frac{5}{12} \end{gathered}$

The correct choice is A.
