</span><span>1/55

</span><span><u>Explanation</u>
</span><span>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
