Hi. Can somebody help me to solve this? Ive been trying to figure this for a week. I'm still confuse if this will need of integrals.
For each of the following, find the constant c so that p(x) satisfies the condition of being a probability density function of a random variable X:
I. p(x) = c(2/3)^x, x ∈ N
II. p(x) = cx, x ∈ {1,2,3,4,5,6}
Hints are very much appreciated. Thanks.
