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
