There are 6 red, 4 green, and 5 yellow marbles in a jar. what is the probability of picking a green marble, then a blue marble if you do not put back the first marble? a.) 1/20 b.) 9/20 c.) 9/40 d.) 1/19

Where are the functions?

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.

Is there more information?
