Question

The probability of selecting a rotten apple randomly from a heap of 900 apples is 0.18. What is the number of rotten apples in the heap?

Answer 1

Total no. of apples=900

Let the no. of rotten apples be=x

Probability of selecting a rotten apple = No. of rotten apples/ Total no. of apples

0.18=x/900
x=900 $\times$ 0.18
x=162
$\therefore$ the total no. of rotten apples = 162
