Question

Suppose the probability of selecting a supermarket shopper who prefers plastic bags instead of paper bags is 50%. Out of 150 shoppers, how many can you expect will prefer plastic bags?(1 point) Responses 70 70 50 50 75 75 100 100

Answer 1

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

Given:
- Total shoppers = 150
- Probability of preferring plastic bags = 50% = 0.5

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

Calculating this:

Expected number = 150 × 0.5 = 75

So, you can expect 75 shoppers to prefer plastic bags.

The correct response is **75**.
