a.

less than Xequals0.3?

b.

greater than Xequals0.3?

c.

between Xequals0.3 and Xequals0.5?

d.

less than Xequals0.3 or greater than Xequals0.5?

a. P(Arrival timeless than0.3)equals

(Round to four decimal places as needed.)

b. P(Arrival timegreater than0.3)equals

(Round to four decimal places as needed.)

c. P(0.3less thanArrival timeless than0.5)equals

(Round to four decimal places as needed.)

d. P(Arrival timeless than0.3 or arrival timegreater than0.5)equals

(Round to four decimal places as needed.)
