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

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
