Stuart draws a card from a deck containing ten cards numbered 1 through 10. He replaces the card and shuffles the deck. If Stuart repeats this process 150 times, approximately how many times will he draw a single-digit card that has an even number?
15
60
75
90

Make sure to explain thanks! :D

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.
