Transcribed Image Text:In a new experiment, a ball is randomly selected from the bowl containing three red and two yellow balls. Its color is noted, and the ball is returned to the bowl before a second ball is selected. Select the additional five simple events that must be added to the sample
space determined in the previous experiment. (Label the five balls as R,, R,, R, Y,, and Y,. Select all that apply.)
In a previous experiment, a bowl contained three red and two yellow balls. Two balls were randomly selected and their colors recorded. A tree diagram was used to list the 20 simple events in the experiment, keeping in mind the order in which the balls were drawn.
