a 3 section spinner which each outcome is not equally likely.if you spin the spinner once,what is the probability that it will stop on a?

I assume you mean that it is a fair spinner (i.e. it stops at any position with equal probability) but the sectors of the spinner are of different sizes.
In this case, the probability of it stopping on "a" is the sector angle of a (in degrees) divided by 360.
If it is not a fair spinner, we don't have an answer.
