Answer:
15/31 or 48.39% or 0.4838
Explanation:
The probability of an event is given by the ratio between the favourable cases and the possible cases.
Since there are 31 loves for the shopper to pick, the number of possible cases is 31
Since we are testing the probability of the shopper picking wheat bread, the favourable cases are the amount of wheat bread that can be picked. 15 in this case
The ratio between the two is 15/31=48.39%
