Answer 1

To find the expected number of shoppers who prefer plastic bags, you can use the probability of preferring plastic bags (50% or 0.5) and multiply it by the total number of shoppers (150).

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

\[ = 0.5 \times 150 = 75 \]

So, you can expect that 75 shoppers will prefer plastic bags.
