geometric probability is a form of theoretical probability determined by a ratio of lengths, areas or volumes. three semicircles with diameters 2, 4 and 6 cm are arranged as shown in the figure. if a point inside the figure is chosen at random, what is the probability that the point is inside the shaded region? remember, a =

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.
