    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
