At the high school 1/3 of the students play an instrument. Of the students who play an instrument 2/3 play a string instrument. What fraction of the students at the high school play a string instrument?

Need the graph to answer this.

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.
