This is the concept of probability and statistics, we are required to find the probability of one girl and 2 boys to be chosen in a group of 4 girls and 6 boys; This information can be modeled by binomial distribution. Here we shall proceed as follows; P(B)=3/5 P(G)=2/5 P(x)=p^(x)(1-p)^(n-x)(nCx) P(x)=(3/5)^6(2/5)^4(10C6) P(x)=0.2508
