Answer:
As, −5/12 belongs to the set of rational numbers, as it is a ratio of two integers −5 and 12 , of which latter is not zero.
The two dice have PMFs
The sum of the two rolls can take on 8 different values:
The outcome of either roll is independent of the other, so that
a. Then PMF of 
is
b. The histogram is nothing special, same as the discrete uniform distribution over the interval [0, 7].
Answer:Yes it is proportional
For num 4 the answer to six is 22 the reason is this formula so write this down for n aswell
n(n+1)/2+1 the example could be as we know for 1 cut we always will have 2 slices so 1(1+1)/2+1 is 2 and for 6 cuts 6(6+1)/2+1 is 22 therefore the answer to 6 cuts is 22 and to n cuts is the formula n(n+1)/2+1
