Tracie spins the four-colored spinner shown below. She records the total number of times the spinner lands on the color red and constructs a graph to visualize her results Which of the following statements is TRUE? O If Tracie spins the spinner 4 times, it will land on red at least once The theoretical probability of the spinner landing on red will change O with every spin completed If Tracie spins the spinner 1,000 times, it would land on red close to (/] © 250 times If Tracie spins the spinner 1,000 times, the relative frequency of it O landing on red will remain constant RATIONALE If we make the assumption that the area of the colors represents the true proportion, then each color is equally weighted. Since there are four colors we would expect them to come up roughly ¥4 of the time. So on 1000 rolls the expected value = n*p = 1000%0.25 = 250.
