Question

There is a bag with only milk and dark chocolates. The probability of randomly choosing a dark chocolate is 5/12. 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

Answer:

35

Step-by-step explanation:

Probability of choosing a milk chocolate = Total Probability - Probability of choosing a dark chocolate

=12/12 - 5/12

=7/12

Let the total number of chocolates be x

Thus-

5/12 of x = 25

5x/12 = 25

5x = 25 × 12

x = 300/5

x = 60

Number of milk chocolates = Total number of chocolates - Number of dark chocolates

=60 - 25

=35

Answer 2

Answer:

Milk chocolates=35

Step-by-step explanation:

Let the total chocolates=x

According to question

5/12 of x = 25

5/12*x=25

5x=25*12

 

5x=300

x=300/5

x=60

milk chocolates=total chocolates-dark chocolates

so, milk chocolates=60-25

so, milk chocolates=35
