Question
There are two spinners containing only black and yellow slices.Spinner A has 4 black slices and 4 yellow slices.All the slices are the same size.Spinner B has 13 black slices and 7 yellow 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 yellow slice.Event 2: Spinner A lands on a red slice.Event 3: Spinner A lands on a black slice.Event 4: Spinner B lands on a black or yellow slice.Least likely Most likelyEvent , Event , Event , Event
Solution
Event 2: Spinner A lands on a red slice. (Least likely, because there are no red slices on Spinner A) Event 1: Spinner B lands on a yellow slice. (There are fewer yellow slices on Spinner B than black slices) Event 3: Spinner A lands on a black slice. (There is an equal chance of landing on a black or yellow slice on Spinner A) Event 4: Spinner B lands on a black or yellow slice. (Most likely, because all slices on Spinner B are either black or yellow)
