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

\n" );
