The random variable X assumes the values 1,2,3 and 4 with equal probability. Find the density functions of the following variates:(adsbygoogle = window.adsbygoogle || []).push({});

Attempted solutions:

X 1 2 3 4

Pr(X) 1/4 1/4 1/4 1/4

a) Y=1-2X

Y -1 -3 -5 -7

Pr(Y) 1/4 1/4 1/4 1/4

b) Z= X/(X+1)

Z 1/2 2/3 3/4 4/5

Pr(Z) 1/4 1/4 1/4 1/4

Are my solutions for parts a and b correct?
