\n" ); document.write( "NOTE: The problem should not be posted this way; without any context, we have to assume that a and b are the minimum and maximum values of the random variable. The problem only makes sense if that is the case -- but the problem should say so, instead of just saying a=10 and b=80.

\n" ); document.write( "The allowable range for the variable is from 10 to 80, a range of 70; the prescribed range for this problem is from 52 to 80, a range of 28. Since the distribution is uniform, the probability that x is greater than 52 is

\n" ); document.write( "28/70 = 2/5 = 40%.
