The procedure for performing a certain task is uniformly distributed on the interval from( a = 32 )minutes to (b= 52) minutes
Generally the cumulative distribution function for continuous uniform distribution is
Generally the probability that it takes more than 46 minutes to learn the procedure is mathematically represented as

=> 
Generally the average time required to learn the procedure is mathematically represented as

=> 
=> 
A=((40+64)/2)*18= 936 units^2
I believe the answer is -1
