Probability and inscribed angle.
See attachment.

Probability:

In $\odot$V, point C is randomly located so that it does not coinside with points R or S. If $m\widehat{RS}=140$, what is the probability that $m\angle RCS=70$?

Hi takersgirl007,

The probability then would be $\frac{220}{360} \:or\: \frac{11}{18}$
