Question 1191932
<font color=black size=3>
It seems like this question is incomplete. 
Are you sure that your teacher wants you to list the possible values of X only?
If so, then it's simply X = 0, X = 1, X = 2, X = 3


If your teacher wants you to also list the corresponding P(X) values, then unfortunately there isn't enough info here. 
It's quite possible that this problem references a previous problem.
If so, then you'll need to post that info as well.
