Answer 1

To find the expected number of shoppers who prefer plastic bags, we can calculate it using the given probability and total number of shoppers.

The probability of preferring plastic bags is 50%, which can be expressed as 0.5.

We can multiply this probability by the total number of shoppers:

Expected number of shoppers preferring plastic bags = \( 0.5 \times 150 = 75 \).

Therefore, you can expect 75 shoppers to prefer plastic bags. So the correct response is:

75
