Question

There are two spinners containing only red and orange slices. Spinner A has 7 red slices and 13 orange slices. All the slices are the same size. Spinner B has 6 red slices and 6 orange slices. All the slices are the same size. Each spinner is spun. List these events from least likely to most likely. Event 1 : Spinner B lands on a red slice. Event 2 : Spinner A lands on a red or orange slice. Event 3 : Spinner A lands on a red slice. Event 4 : Spinner B lands on a black slice.

Answer 1

Event 4 (impossible), Event 3 (probability is 7/20), Event 1 (probability is 6/12 which is greater than 7/20), and Event 2 (certain to happen)
