Answer 1

To determine the expected number of supermarket shoppers who prefer plastic bags, you can multiply the total number of shoppers by the probability of a shopper preferring plastic bags.

Given:

• Probability of preferring plastic bags = 50% = 0.5
• Total number of shoppers = 150

Expected number of shoppers who prefer plastic bags = Total shoppers × Probability of preferring plastic bags = 150 × 0.5 = 75

So, the expected number of shoppers who prefer plastic bags is 75.
