Algebra.Com's Answer #232770 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! In a certain lottery, 3 different numbers between 1 and 8 inclusive are drawn at random. These are the winning number. If you choose 3 different numbers at random between 1 and 8, what is the probability you will match the winning numbers? Assume that the order of the numbers is unimportant. \n" ); document.write( "-------------------- \n" ); document.write( "It's not specified, but to get that answer: \n" ); document.write( "No repeats are allowed, ie, 888 is not valid. \n" ); document.write( "------------- \n" ); document.write( "The 1st number is one of 8, then 1 of 7, then 1 of 6. \n" ); document.write( "= 8*7*6 \n" ); document.write( "But since is says order doesn't matter, 876 is the same as 678 and 786, etc \n" ); document.write( "That gives each possible number 6 different ways it can be selected. \n" ); document.write( "--> 8*7*6/6 \n" ); document.write( "= 8*7 \n" ); document.write( "= 1/56 \n" ); document.write( " \n" ); document.write( " |
