Determine the value c so that each of the following
functions can serve as a probability distribution of
the discrete random variable
x: (a)
f(x) =c(x2+ 4), for x= 0,1,2,3;
(b)f(x) =c(choose x from2)(choose 3 from 3-x) for x= 0,1,2.

This can help you

a) since it is discrete we need to think about the sum thing it it was continuous we would look at an integral thing so I think if I remember correctly we need to find c such that ∑i=03c(x2+4)=1
b)  problem b is a similar setup

Hey mate here is the answerthe correct answer is b may it will you
