Algebra.Com's Answer #210843 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! The access code for a garage door consists of three digits. Each digit can be 2 through 8 and each digit can be repeated. \n" ); document.write( "1) The number of possible access codes is? \n" ); document.write( "2 thru 8 --> 7 possibilities \n" ); document.write( " \n" ); document.write( "343 possible codes \n" ); document.write( "---------------- \n" ); document.write( "2) The probability of randomly selecting the correct access code is (rounded to the nearest thousandth)? \n" ); document.write( "1 out of 343 = 1/343 =~ 0.003 \n" ); document.write( "---------------------------- \n" ); document.write( "3) The probability of not selecting the correct access code is (round to the nearest thousandth)? \n" ); document.write( "That's 1 minus the probability of getting it. \n" ); document.write( "= 1 - 1/343 \n" ); document.write( "=~ 0.997 \n" ); document.write( " \n" ); document.write( " |
