It says Quiz 1 and the score box is missing.


Problem 2a)
1. I think the answer should depend on d, n, D and g 
2. Do the couple make their first payment right after the g years of grace period? I think\
   so but if I were a student I would like the wording to be a bit more explicit.


Problem 3a)
Do we accept the answer where a student just give a factorization of 1111111? (I 
am not sure how difficult it is). Perhaps maybe we should add something like "answers by 
simply giving a factorization is not accepted"...



Problem 4
Can students simply write down solutions for the parts?

4a) Maybe we should specify each deck contains 52 distinct cards



Problem 5a)
Suppose a confused student asks what are they supposed to do in this part (or 
where should they fill in answers), are we allowed to explain to him "to write the 
appropriate probabilities on each edge and leave"?  Perhaps adding answer boxes would
avoid the confusion.
