The expected number of shoppers who prefer plastic bags can be calculated by multiplying the probability by the total number of shoppers:
0.50 (probability of preferring plastic bags) * 150 (total shoppers) = 75
Therefore, you can expect 75 shoppers out of 150 to prefer plastic bags.
Therefore, the answer is 75.
0.50 (probability of preferring plastic bags) * 150 (total shoppers) = 75
Therefore, you can expect 75 shoppers out of 150 to prefer plastic bags.
Therefore, the answer is 75.
