Look at the possible outcomes.
There are 2%5E4 or 16 of them.
Also list the number of girls for each outcome.
GGGG-4
GGGB-3
GGBG-3
GGBB-2
GBGG-3
GBGB-2
GBBG-2
GBBB-1
BGGG-3
BGGB-2
BGBG-2
BGBB-1
BBGG-2
BBGB-1
BBBG-1
BBBB-0
So then sum up each occurrence for the number of girls,
4G:1
3G:4
2G:6
1G:4
0G:1
So then the probability would be the number of outcomes divided by the total number of outcomes,
4G:P%284G%29=1%2F16
3G:P%283G%29=4%2F16=1%2F4
2G:P%282G%29=6%2F16=3%2F8
1G:P%281G%29=4%2F16=1%2F4
0G:P%280G%29=1%2F16
