Carol, you have now posted this question 3 times

You never cleared up any of these concerns, and reposted it exactly the same way.
It is still equally confusing.
Did you not read my reply? 
Reiny I just read your replies but this is hoe the question is worded. That is why I myself do not understand it

Sorry I meant how the question is worded.

In that case I don't know how to answer the question.
Perhaps somebody else can shed some light on it. 
This is not how the problem is worded. This is the problem. Three different people are to be selected at random, and each will be given one gift card. There is one card from Home Depot, one from Best Buy, and one from Red Lobster. The first person selected gets to choose one of the cards. The second person selected gets to choose between the two remaining cards. The third person selected gets the third card.
A) Determine the number of points in the sample space.
B) Construct a tree diagram and determine the sample space.
Determine the probability that
C) The Best Buy card is selected first
D) The Home Depot card is selected first and the Red Lobster card is selected last.
E) The cards are selected in this order: Best Buy, Red Lobster, Home Depot.
