You can put this solution on YOUR website!
There's a couple of ways of doing this:
\n" ); document.write( "The multiplication rule:
\n" ); document.write( "Multiply the probabilty of having a boy and a boy and a boy and a boy.
\n" ); document.write( "\"P=%281%2F2%29%281%2F2%29%281%2F2%29%281%2F2%29=1%2F16=.0625\"
\n" ); document.write( "You can also raise the probability to the power of 4.
\n" ); document.write( "\"P=%281%2F2%29%5E4\"
\n" ); document.write( "\"P=1%2F16=.0625\"
\n" ); document.write( "If you aren't to that point in your book, P=(#of ways to have 4 boys)/(# of ways to have children)
\n" ); document.write( "There is 1 way to have 0 boys: (GGGG)
\n" ); document.write( "There are 4 ways to have 1 boys: (BGGG),(GBGG),(GGBG),(GGGB)
\n" ); document.write( "There are 6 ways to have 2 boys: (BBGG),(GBBG),(GGBB),(BGBG),(GBGB),(BGGB)
\n" ); document.write( "There are 4 ways to have 3 boys: (BBBG),(BBGB),(BGBB),(GBBB)
\n" ); document.write( "There is 1 way to have 4 boys:(BBBB)
\n" ); document.write( "There is 1 way to have 4 boys and 16 ways to have 4 children:
\n" ); document.write( "\"highlight%28P=1%2F16=.0625%29\"
\n" ); document.write( "Happy Calculating!!!
