Answer

Explanation:

Step1: Calculate the proportion of fedoras

The proportion of fedoras in the first - batch is $\frac{4}{20}=\frac{1}{5}$.

Step2: Use the proportion to predict

Multiply the proportion by the number of new hats. So the expected number of fedoras in 15 hats is $\frac{1}{5}\times15 = 3$.
