Question

There is a bag with only milk and dark chocolates.

5
The probability of randomly choosing a dark chocolate is 1
12
There are 25 dark chocolates in the bag and each is equally likely to be chosen.
Work out how many milk chocolates there must be.

Answer 1

There are 300 milk chocolates in the bag.

Explanation:

Since there is a bag with only milk and dark chocolates, and the probability of randomly choosing a dark chocolate is 1/12, if there are 25 dark chocolates in the bag and each is equally likely to be chosen, to determine how many milk chocolates there must be the following calculation must be performed:

1 = 25

12 = X

12 x 25/1 = X

300/1 = X

300 = X

Therefore, there are 300 milk chocolates in the bag.
