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?
We know that Probability of an event E = `"Number of favourable outcomes"/"Total number of outcomes"`
Let E be the event of selecting rotten apple.
Let n be the number of rotten apples in the heap.
`P(E) = n/900`
`=> 0.18 = n/900`
`=> n = 162`
Thus total rotten apples = 162
