Hi everyone,
So I am taking a statistics course and finding this concept kinda challenging. wondering if someone can help me with the following problem!
Suppose X is a discrete random variable with moment generating function
M(t) = 2/10 + 1/10e^t + 2/10e^(2t) + 3/10e^(3t) + 2/10e^(4t)
where t is a real number.
we want to find the probability function of X.
I know that M(t) = E(e^(tx)) = e^(tx)* f(x)
but not sure what to do from there.
Thanks for the help ^^
