Once a customer fills the car with gas at one station, that customer cannot then go fill the same car with gas at another station right away. Are the outcomes E1, E2, E3, and E4 mutually exclusive? Explain.

yes : - P (Ei ∩ Ej) = 0

Step-by-step explanation:

These are mutually exclusive events

that is, a customer can only go to a gas station to fill his car with gas par time

P (E1) = 1/4

P (E2) = 1/4

P (E3) = 1/4

P (E4) = 1/4

summation of the four probabilities give 1
