Algebra.Com's Answer #305234 by htmentor(1343)![]() ![]() You can put this solution on YOUR website! The total probability is the product of the individual probabilities. \n" ); document.write( "The probability of getting a particular number, in this case a 3, out of the eight possible numbers is: \n" ); document.write( "P(1st number is 3) = 1/8 \n" ); document.write( "Out of the 8 numbers, 4 are even. Therefore: \n" ); document.write( "P(even number) = 4/8 = 1/2 \n" ); document.write( "So the total probability is: \n" ); document.write( "P(3 and even) = 1/8*1/2 = 1/16 \n" ); document.write( " |
