probability it is friday and it's your day off is 12%.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the probability that your work day is friday is 1/5.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the formula for p(a given b) is:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "p(a given b) is equal to p(a and b) / p(b)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "if you let a be the probability that it is your day off and you let b equal the probability that it is friday, then you get:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "p(a and b) = 12% = .12.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "p(b) = 1/5 = 20% = .2.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "p(a given b) = p(a and b) / p(b) becomes:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "p(a given b) = .12 / .2 = .6.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "that's what i think the answer is for this problem.\r
