Algebra.Com's Answer #231841 by Fombitz(32388) You can put this solution on YOUR website! 1a) 4 aces in 52 cards, P(ace)=4/52=1/13 \n" ); document.write( "1b) P(6)=4/52, P(heart)=13/52, P(6 of hearts)=1/52 \n" ); document.write( "P(6 or heart)=P(6)+P(heart)-P(6 of hearts)=4/52+13/52-1/52=16/52=4/13 \n" ); document.write( "1c) P(9)=4/52, P(spade)=13/52, P(9 of spades)=1/52 \n" ); document.write( "P(9 or spade)=4/13 \n" ); document.write( "P(not 9 or spade)=1-4/13=9/13 \n" ); document.write( ". \n" ); document.write( ". \n" ); document.write( ". \n" ); document.write( "2) I assume you mean they are drawn without replacement. \n" ); document.write( "P(diamond)=4/52=1/13 \n" ); document.write( "P(heart)=4/51 \n" ); document.write( "P(diamond, heart)=(1/13)(4/51)=4/663 \n" ); document.write( " |
