Number black are 26 \n" ); document.write( "number even are 20 \n" ); document.write( "that's 46. \n" ); document.write( "But I double counted black cards that are even, and there are 10 of them. \n" ); document.write( "the answer is 36/52=9/13 \n" ); document.write( "=========================== \n" ); document.write( "That is also the answer to b. \n" ); document.write( "=========================== \n" ); document.write( "Neither black nor even is the complement or 1- the probabilty. \n" ); document.write( "1-(9/13)=(4/13) \n" ); document.write( " |
