Algebra.Com's Answer #680430 by Boreal(15235)![]() ![]() You can put this solution on YOUR website! For a single die, the probability no 5 or 6 appears is (2/3) \n" ); document.write( "For six of them, the probability is (2/3)^6=0.0878. \n" ); document.write( "For a single die, the probability of one 5 is (1/6). The probability of no 6 is (5/6)^5. That is 0.0670. \n" ); document.write( "There is the same probability of one 6 and no 5, 0.0670, and these three probabilities, which are not desired, is 0.2218. \n" ); document.write( "Therefore, the probability of at least one 5 and one 6 is 0.7782. \n" ); document.write( " |
