Algebra.Com's Answer #512256 by jim_thompson5910(35256)![]() ![]() ![]() You can put this solution on YOUR website! In a standard deck, the red cards are hearts and diamonds. There are \"8 hearts, 8 diamonds\", so 8+8 = 16 red cards.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "There are \"8 hearts, 8 diamonds, 6 spades, and 6 clubs\", so 8+8+6+6 = 28 cards total\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "The experimental probability is the number of things we want over the number of things total, so...\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "experimental probability = (# of things we want)/(# of things total)\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "experimental probability that card is red = (# of red cards)/(# of cards total)\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "experimental probability that card is red = 16/28\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "experimental probability that card is red = 4/7 ... make sure to reduce all fractions\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So the answer is 4/7 \n" ); document.write( " |
