Question 1191932: Suppose three iphones are tested random. We want to find out the number of defective iphones that occur. Thus, to each outcome in the sample space we shall assign a value. These are 0,1,2, or 3. If there is no defective iphone, we assign the number 0; if there is 1 defective iphone, we assign the number 1; if there are two defective iphones, we assign the number 2; and 3, if there are three defective Iphones. The number of defective iphones is a random variable. The possible values of this random variable are 0,1,2, and 3.
Let D represent the defective iphone and N represent the non-defective iphone. If we let X be the random variable representing the number of defective cell phones, show the values of the random variable X by using table.

You can put this solution on YOUR website!
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.
