Answer:
80 chocolates type 'a' and 240 chocolates type 'b"
Explanation:
if the company selects 2000 random chocolates of each type we ca predict that the amount of chocolates that have an incorrect weight will be:
Type 'a': 2000x0.04 = 80
Type 'b': 2000x0.12 = 240
The company is expected to find 80 chocolates type 'a' and 240 chocolates type 'b' that have incorrect weight.
