(b) The first person selected is not a pledge.


(c) The second person selected is a pledge if the first person selected was also a pledge.


(d) The second person selected was a full member if the first person selected was a pledge.


(e) The second person selected is a pledge if the first person selected was a full member.


(f) The second person selected is a full member if the first person selected was also a full member.

What are your thoughts about these problems?

Tell us - and we'll go from there.
