how many times will the inscribed angle fit in the central angle?
2 times Remember the measure of an arc is
equal to the measure of the central angle that intercepts it. Therefore, the measure of an inscribed angle is _______________ the measure of the intercepted arc
½ Inscribed angle theorem
Measure of angle B = ½ measure of arc AC

View videos on sports, weather How is probability used in the real-world? Probability of an event is represented as
a fraction or decimal from 0 to 1 or percent 0% to 100%
0 probability is impossible

Relative frequency – How often something happens divided by all outcomes. Example: if your team has won 9 games from a total of 12 games played:
Geometric probability – points on a segment or in a region of a plane represent outcomes. The geometric probability of an event is a ratio that involves geometric measures such as lengths of segments or areas of regions
P (event) = # favorable outcomes/ # possible outcomes
