Solution :
Given that there is only one set which can contain all the five correct answers. While guessing that I am likely to choose only one sequence of the answers as another, then the probability of getting all the five answers correct is given by :
Given : X
binomial 
P (X = 5)

= 0.00412
Thus the probability is 0.00412

Average is the total of x divide by number of x.
Here, we have,
x = 55, 64, 60, 61
number of x = 4
Total of x = 55 + 64 + 60 + 61 = 240
So, the average is,
240 / 4 = 60
