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

Let the no. Of rotten apples be x.

Therefore, possible outcomes=900

Favourable outcomes=x

According to condition, Probability(rotten apple) =x/900

Or, 0.18=x/900

Or,x=0.18*900=162

No. Of rotten apples =162(ans).
