This is OK just complete the calculation of the marginal distribution

P(X2=0|X1=2) = 0.08/P(X1=2) = 0.08/0.28 = 0.2862-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

P(X2=1|X1=2) = 0.05/P(X1=2) = 0.05/0.28 = 0.179

P(X2=2|X1=2) = 0.15/P(X1=2) = 0.15/0.28 = 0.536
