Suppose the probability of selecting a supermarket shopper who prefers plastic bags instead of paper bags is 25% of the 120 shoppers how many can you expect will prefer plastic bags

Answer 1

You can expect 30 shoppers to prefer plastic bags. This is calculated by multiplying the total number of shoppers (120) by the probability of selecting a shopper who prefer plastic bags (25% or 0.25):

120 shoppers * 0.25 = 30 shoppers

Therefore, you can expect 30 shoppers out of 120 to prefer plastic bags.
