Answer:
b) 4 dozen
Explanation:
The computation of the optimal number of specially bagels i.e expected value is shown below:
As we know that
Expected value = Demand × probability
= 1 dozens × 0.10 + 2 dozens × 0.15 + 3 dozens × 0.20 + 4 dozens × 0.25 + 5 dozens × 0.30
= 0.1 + 0.3 + 0.6 + 1 + 1.5
= 3.5 dozen or 4 dozen
Hence, the correct option is b.
