Let X be a discrete random variable that can assume the values -1, 0,1,2,3,4 with the probabilities 1/6, 1/12, 1/6, 1/4, 1/12, 1/4. Find the probability densities of the following random variables:
a) Z= X^2 + 1
h(y)= f(g^-1(y))
Attempted Solution
X= -1 0 1 2 3 4
Z= 2 1 2 5 10 17
How do i find Pr(Z)?
The book gave an answer of
1/12 Z=1,10
1/4 Z= 5,17
1/3 Z=2
