Not enough information - are there 18 yellow balls?
If so, you are trying to calculate the probability at least one of the balls is yellow,
P(no balls are yellow)=P(first ball is non-yellow)×P(second ball is non-yellow)
P(no yellow)=1230×1129
P(at least one yellow)=1−P(no yellow)
You can also calculate the probability of one ball being yellow and them both being yellow:
P(both)=1830×1730
P(one)=P(first is yellow and second is not)+P(second is yellow and first is not)=1830×1229+1230×1829
which is just 2×P(first is yellow and second is not).
Honestly though, this looks just like a homework problem
