What is the probability of getting 2 hearts or 2 numbers les than 4 (count aces as one. \n" ); document.write( "---------- \n" ); document.write( "Probability of getting two hearts = [13C2]/52C2 \n" ); document.write( "Probability of getting 2 numbers less than 4 = 12C2/52C2 \n" ); document.write( "These are mutually exclusive results so: \n" ); document.write( "Prob(2hearts or 2 numbers <4) = P(2 hearts) + P(2 numbers <4) \n" ); document.write( "={[13C2}+12C2]/52C2} \n" ); document.write( "={78+66]/1326 \n" ); document.write( "=0.1085972851... or about 11% \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
