Algebra.Com's Answer #374724 by John10(297) You can put this solution on YOUR website! In a normal deck, we have 26 red cards and 26 black cards \n" ); document.write( "The first red card is 26/52 or 1/2 \n" ); document.write( "The next black card is 26/51 \n" ); document.write( "The next black card is 25/50 or 1/2 \n" ); document.write( "Assume we can not replace the card back into the deck after took it out.\r \n" ); document.write( "\n" ); document.write( "So the probability is: (1/2)*(26/51) *(1/2) = 26/204 or 13/102 = 0.127\r \n" ); document.write( "\n" ); document.write( "Hope it helps:) \n" ); document.write( "John10 \n" ); document.write( " \n" ); document.write( " |
