Algebra.Com's Answer #734442 by greenestamps(13215) You can put this solution on YOUR website! \n" ); document.write( "I can't imagine what it would be about this problem that you need help with, unless you don't understand the meaning of the data that is presented to you. \n" ); document.write( "The meaning of the given information is \n" ); document.write( "P(5) = 0.2 \n" ); document.write( "P(6) = 0.1 \n" ); document.write( "P(7) = 0.1 \n" ); document.write( "P(8) = 0.2 \n" ); document.write( "P(9) = 0.4 \n" ); document.write( "Notice that the sum of the probabilities is 1, as it must be, because 5 through 9 are the only values x can have. \n" ); document.write( "Then the number you are supposed to find is P(x greater than 6); that means x is 7, 8, or 9. Surely you know how to evaluate something like P(7 OR 8 OR 9).... \n" ); document.write( "If you still don't understand, re-post the problem saying what it is about the problem that you don't understand. \n" ); document.write( " |
