There are 8 streets to be named after 8 tree types. Ash, Birch, Cedar, Elm, Fir, Oak, Spruce, and Willow. A city planner randomly selects the street names from the list of 8 tree types. Compute the probability of each of the following events. Event A: The first street is Spruce, followed by Birch and then Oak. Event B: The first three streets are Spruce, Fir, and Ash, without regard to order. Write your answers as fractions in simplest form. P(A) = [| P(B) = ]
