Answer:
It is impossible to simulate this with a random number generator without knowing what the correct answer choices were 
Step-by-step explanation:
Given

How can he select the right answer
Using randint will only generate a random number which could or could not be the answer to the question. 
This is so because each of the 5 options for the question has the same probability of 1/5. So, using randint will only generate a random number. This generated random number has 1/5 chance of being the answer and 4/5 of not being the answer to the question.
In a nutshell, he can not make use of a simulator to select the answer to the questions in this scenario, unless he knows the solution.
<em>Hence (a) answers the question.</em>
 
        
             
        
        
        
Step-by-step explanation:
a rectangular prism (like this brick) has the same basic structure as a cube (like a die) : it has 6 sides.
while a die has 6 equal sides, a rectangular prism has 3 pairs of equal sides :
top and bottom
left and right
front and back
all we have to do is calculate the areas of the 6 rectangles and add them up. that's it.
your remember, the area of a rectangle is
length × width
in our case we have
top and bottom : 2.5×11.5 × 2 = 28.75×2 = 57.5 in²
left and right : 2.5×5 × 2 = 12.5×2 = 25 in²
front and back : 11.5×5 × 2 = 57.5×2 = 115 in²
so, the total surface area of the whole block is
57.5 + 25 + 115 = 197.5 in²
 
        
             
        
        
        
78÷18=4.3333333
so it's 4.33333 many pancakes with one cup 
so then you multiply 4.33333... by 12 which equals 52
So you can make 52 pancakes with 12 cups of flour
