In order to solve or know the probability of having 2 girls and 2 boys, assumed that a girl is as likely as a girl at each birth, pascal’s triangle will be likely used. And we will be referring to the line 4 of pascal’s triangle, which was 1 4 6 4 1. Then it will look like this: 1 = 4 girls; 4 = 3 girls & 1 boy; 6 = 2 girls & 2 boys; 4 = 3 boys & 1 girl; 1 = 4 boys. And now for the solution in order to get the probability of having 2 girls and 2 boys is to divided into the sum of 1+4+6+4+1.
