Answer 1

To find the probability of a moth being black, you need to divide the number of black moths by the total number of moths.

The number of black moths = 35
The total number of moths = 50 (brown) + 15 (yellow) + 35 (black) = 100

Now calculate the probability:

\[
\text{Probability of black moth} = \frac{\text{Number of black moths}}{\text{Total number of moths}} = \frac{35}{100} = 0.35
\]

To express this as a percentage:

\[
0.35 \times 100 = 35\%
\]

So, the probability of a moth being black is **35%**.
