# Math Help - Probability and inscribed angle.

1. ## 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} \r\: \frac{11}{18}" alt="\frac{220}{360} \r\: \frac{11}{18}" />
