for the 1st part draw a tree diagram 

|dw:1366674265718:dw|

you can finish the last stage of the tree diagram... the diagram will also give all the possible outcomes. 

for part (b)

just find the number of outcomes that sum to 7 and put that over the total number of outcomes. 

hope this helps
