Question

Suppose event a=energy efficient and event b=used. You buy a used car that is energy efficient. The combination of events that represents your purchase is:

1) a
2) b
3) a and b
4) neither a nor b

Answer 1

The combination of events that represents the purchase of a car that is both used and energy efficient is event A and event B, option (3).

Step-by-step explanation:

The combination of events A and B, signifies the occurrence where you purchase a car that is both energy-efficient and used. In probability theory, the intersection of events A and B represents the outcomes that satisfy both conditions simultaneously. This implies that your choice aligns with both criteria of purchasing an energy-efficient car and opting for a used vehicle.If event A represents purchasing an energy efficient car and event B represents purchasing a used car, and you buy a car that is both used and energy efficient, the combination of events that represents your purchase is event A and event B. This is because both conditions or events apply to your purchase. Therefore, the correct answer is (3) A and B, meaning the car is both energy efficient and used.
