The probabilities that two students will not show up for class on a beautiful spring day are 0.3 and 0.4, respectively. it is a beautiful spring day. find the following probabilities. (see example 6. round your answers to two decimal places.) (a) neither will show up for class. (b) both will show up for class. (c) exactly one will show up for class.

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.
