This question is asking for the expected value, which is calculated by multiplying the total number of shoppers by the probability of selecting a shopper who prefers plastic bags.
Expected value = Total shoppers * Probability of selecting shopper who prefers plastic bags
Expected value = 150 * 0.50
Expected value = 75
Therefore, you can expect that out of 150 shoppers, 75 will prefer plastic bags.
