Question

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

Answer 1

Here,
Probability=(No. of rotten apples)/(Total no. of apples)
0.18=x/900
X=900×0.18=162

Answer 2

total no. of apples=900
let the no. of rotten apples be=x
probability of selecting a rotten apple=no. of rotten apples/ total apples
0.18=x/900
x=900*0.18
x=162
therefore the total no. of rotten apples = 162    answer
