Answer 1

2/20 is the first @Zarkon

Answer 2

there are 3+2+6+9 = 20 marbles
there are 2 yellow marbles

probability of selecting a yellow marble is simply the number of yellow marbles in the bag / the number of marbles in the bag

you have to available choices (2 yellow) from a total of
3+2+6+9 marbles, so 2/(3+2+6+9)
