Question 11

Explanation

Identifying the Information

It is known that the total number of eggs in the box is $40$. Of these, $3$ are rotten. We are asked to find the probability of selecting a non-rotten egg.

Calculating the Number of Non-Rotten Eggs

The first step is to determine the number of favorable outcomes, which is selecting an egg in good condition. Since there are $3$ rotten eggs out of a total of $40$, the number of non-rotten eggs is the difference.

Calculating the Probability

The probability of an event is calculated by dividing the number of favorable outcomes by the total number of possible outcomes (sample space).

Thus, the probability of selecting one non-rotten egg is $\frac{37}{40}$.
