My answer is 3. I got the answer by dividing 15 by 45. 15 is the probability of choosing white. 45 is the probability of choosing one among 45.

There are total 45 chocolates in a box.
20 RED, 15 WHITE, 10 BLACK. So , We need to choose a white one. It can be selected only from 15 white chocolate .So, 15C1(no of chocos C 1 ->i.e we need only one choco). From 45 chocolates we need to choose any one randomly so again 45C1 PROBABILITY IS =15C1/45C1=1/3

Is this solution Helpfull? Yes | No
