a) red=#9/39#

blue=#13/39#

green=#17/39#

Second choice, these fractions would all have denominators of 38.
Reading down from the top:
8, 13, 17, 9, 12, 17, 9, 13 and 16

b) looking at the tree diagram there are 9 final boxes - this is how many ways you can select the marbles.

Selecting exactly one blue is 4, (r,b) (b,r) (b,g) and (g,b)

P(2reds)=# 9/39xx8/38=12/247#

P(g,r)=#17/39xx9/38=153/1482#
