Question

A factory inspector found flaws in 2 out of 12 wooden boxes. What is the experimental probability that the next wooden box will be flawed?

Write your answer as a fraction or whole number.

Answer 1

The experimental probability that the next wooden box will be flawed is $\frac{3}{13}$

Explanation:

Given:

2 out of 12 wooden boxes is flawed.

Experimental probability that the next wooden box will be flawed = ?

If next wooden box is inspected, the total number of wooden box checked will be 12 + 1 = 13

If the next wooden box is flawed, then the number of flawed boxes would be 2+1 = 3

Thus, the experimental probability that the next wooden box will be flawed is $\frac{3}{13}$
