2 Answers

The number of outcomes for the two spins are GG,GB, BB, BG and any of these 4 are equally likely.
So the number of ways to succeed i.e.BG is 1 so the probability of BG in two spins is 1/4 or .25. 
Make sense?

the first spin could land on blue and the second spin could land on blue
bb
the first spin could land on blue and the second spin could land on gray
bg
the first spin could land on gray and the second spin could land on gray
gg
the first spin could land on gray and the second spin could land on blue
gb
 
there are four possibilities: bb, bg, gg, gb
the probability is 1/4
