3. A group consists of 4 men and 3 women.
\n" ); document.write( "a) In how many ways can 3 people be selected from the group of 7?
\n" ); document.write( "7C3
\n" ); document.write( "= 7!/3!(7-3)!
\n" ); document.write( "= 4!(5*6*7)/3!4!
\n" ); document.write( "= (5*6*7)/3!
\n" ); document.write( "= (5*6*7)/(1*2*3)
\n" ); document.write( "= (5*6*7)/(2*3)
\n" ); document.write( "= (5*6*7)/(6)
\n" ); document.write( "= (5*7)
\n" ); document.write( "= 35
\n" ); document.write( ".
\n" ); document.write( "b) In how many ways can 3 people be selected if they are all men?
\n" ); document.write( "4C3
\n" ); document.write( "= 4!/3!(4-3)!
\n" ); document.write( "= 4!/3!1!
\n" ); document.write( "= 4!/3!
\n" ); document.write( "= 3!(4)/3!
\n" ); document.write( "= 4
\n" ); document.write( ".
\n" ); document.write( "c) What is the probability that the selected group will be all men?
\n" ); document.write( "4/35 = 0.11 = 11%
\n" ); document.write( "
\n" );
