Suppose an experiment has outcomes black, white, red, orange, yellow, green, blue, and purple, where each outcome has an equal chance of occurring. Let event C = {green, blue, purple} and event P = {red, yellow, blue}. Then
C AND P = {blue} and C OR P = {green, blue, purple, red, yellow}. Draw a Venn diagram representing this situation.
Approximately of Americans commute to work by car, truck, or van. Out of that group, drive alone anddrive in a carpool. Approximately walk to work and approximatelytake public transportation.
a. Construct a table or a tree diagram of the situation. Include a branch for all other modes of transportation to work.
b. Assuming that the walkers walk alone, what percent of all commuters travel alone to work?
c. Suppose that workers are randomly selected. How many would you expect to travel alone to work?
d. Suppose that workers are randomly selected. How many would you expect to drive in a carpool?
