$$P(Desirable\ event)=\frac{Measure\ of\ Desirable\ Outcomes}{Measure\ of\ Total\ Outcomes}$$
This measure could be of any type, area, time period, sets, etc. In this case it is degrees.
The total outcomes all come within $360^\circ$. So,
$$P(Point\ lies\ in\ given\ angle)=\frac{63^\circ}{360^\circ}=\frac7{40}$$
