To find the expected number of shoppers who prefer plastic bags, you 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 = 150 × 0.5 = 75

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