A family has 8 girls and 4 boys. a total of 3 children must be chosen to speak on behalf of their family at a local benefit. what is the probability that no girls and 3 boys will be chosen

Answer

1/55

Explanation

The probability of an event is a chance of it happening. It is calculated as;

Probability = (fouvarable outcome) / (total outcome)

Since we are finding the probability of no girl will be chosen, it is like finding the probability of choosing 3 boys.

The probability of choosing the first boy = 4/12

The probability of choosing the second boy = 3/11

The probability of choosing the third boy = 2/10

The probability of choosing the 3 boys will be,

=4/12*3/11*2/10

=24/1320

=1/55
