You want to find the value of x for which the area under the curve to the left of x is 0.6. One way to do that is to create the cumulative distribution function (CDF) for the given PDF, then see where it is equal to 0.6.
Doing that, we find a = 5.
To find the mean you add all the numbers then divide by how many numbers there are :
8+16+12+11+8=55
in the equation there are 5 numbers, so you divide 55 by 5 :
55÷5=11
the mean is 11
