Question

The probability of selecting a rotten apple from a heap of 900 apples is 0•18.What is the number of rotten apples in the heap?

Answer 1

Total number of apples = 900

Let the number of rotten apples be = x

Probability of selecting a rotten apple = Number of rotten apples / total apples

0.18 = x/900

x = 900*0.18

x=162

Therefore the total number of rotten apples = 162

Answer : 162
