@odoimag1 The 16-member sample space for gender of four children is as follows: GGGG GGGB GGBG GBGG BGGG BBGG BGGB BGBG GBBG GGBB GBGB BBBG BBGB BGBB GBBB BBBB

Count those which have 2 Gs, 3 Gs, and 4 Gs to calculate the number of families with at least two girls. Then, divide that by 16, the number of possible outcomes, to get the probability.
