Algebra.Com's Answer #236731 by jim_thompson5910(35256)![]() ![]() ![]() You can put this solution on YOUR website! If order doesn't matter, then you are correct in saying that 12 C 5 = 792\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "a) The sample space is just the set of all possible items that you can select. In this case, the sample space is the set of 52 cards that you can select from.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "b) Correct. There are 4 suits and 3 face cards (Q, J, K). So there are 12 face cards total out of 52 cards which means that the probability is about 12/52=0.230769 or about a 23.0769% chance \n" ); document.write( " |
