0.18 probability means there are 18 apples rotten in 100 apples.
which means there are 18×9 apples rotten in 900 apples.
therefore 162 apples are rotten in all.

Answer 2

Probability=0.18


Now total no of apple= 900

Now we know that

Prob= selected randomly/total no
0.18= rotten apple/900

Ie rotten ape = 900×0.18
