A. Probability(P) of 3 red is (3/12) * (2/11) * (1/10) = 0.0045
\n" ); document.write( "P of 3 green is (4/12) * (3/11) * (2/10) = 0.0182
\n" ); document.write( "P of 3 yellow is (5/12) * (4/11) * (3/10) = 0.0455
\n" ); document.write( "P of 3 red or 3 green or 3 yellow = 0.0045 + 0.0182 + 0.0455 = 0.0682
\n" ); document.write( ":
\n" ); document.write( "B. P of 3 different colors = (3/12) * (4/11) * (5/10) = 0.0455
