Given any two events, E1 and E2, what does the probability P(E1 ∪ E2) represent? A.
One of the events occurs, or both occur.

B.
Neither event occurs.

C.
Both of the events occur.

D.
One of the events occurs but not both.

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.

Ibelieve the answer is c i worked it out three times but if my answer is wrong someone correct me
