Answer 1

To find the expected number of shoppers who prefer plastic bags, you can multiply the total number of shoppers by the probability of selecting a shopper who prefers plastic bags.

Given:
- Total number of shoppers = 150
- Probability of preferring plastic bags = 50% = 0.50

Expected number of shoppers preferring plastic bags = Total shoppers × Probability

= 150 × 0.50
= 75

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

**75**
