the probability of a male being color blind is 1/10
\n" ); document.write( "the probability of a female being color blind is 1/7
\n" ); document.write( "the probability of a person being selected being male is .5
\n" ); document.write( "the probability of a person being selected being female is .5\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "50% of the time you will select a male.
\n" ); document.write( "50% of the time you will select a female.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "p(male) = .5
\n" ); document.write( "p(female) = .5
\n" ); document.write( "p(person) = .5 + .5 = 1\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "p(color blind male) = 1/10 = .1
\n" ); document.write( "p(color blind female) = 1/7 = .142857143
\n" ); document.write( "p(color blind person) = .5*.1 + .5*.142857143 = .121428571\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
