Algebra.Com's Answer #665480 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! The question asks to find probability of getting both a number greater than 2 and an even number. \n" ); document.write( "So: P(> 2 and even) = P(> 2) + P(even) = 2/3 + 1/2 = 7/6 \n" ); document.write( "------- \n" ); document.write( "P(> 2 AND even) \n" ); document.write( "Only 4 and 6 are greater than 2 AND even. \n" ); document.write( "Ans: P(>2 AND even) = 2/6 = 1/3 \n" ); document.write( "------------ \n" ); document.write( "Also:: P(>2 AND even) = P(>2)*P(even) = (4/6)(3/6) = 12/36 = 1/3 \n" ); document.write( "-------------- \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "--------------- \n" ); document.write( " |
