Hi,

I would like some help with this problem

If X1 and X2 are two discrete random variables with joint probability distribution given by the following bivariate table.(table attached)

1- Find the probability distributuon of X1

here I did:

P(X=0)=0.05+0.15+0.05=0.25

P(X=1)=0.04+0.1+0.06=0.20

P(X=2)=...

P(X=3)=...

.

2-Find the conditional probability distribution of X2 given X1=2.

here I did:

P(X2|2)=0.08+0.05+0.15

But I am not sure.

thank you
