Question

SAS has 12 daily flights from Oslo-Gardermoen to Copenhagen and Norwegian has 18 daily flights during the period from January to April. Due to the snowy weather, the probability of a random SAS aircraft being delayed is 0.15 while the corresponding for Norwegian aircraft is 0.20. We define the following events

S = a random SAS aircraft

N = a random Norwegian aircraft

F = a random aircraft which is delayed

a. What are P (S), P (N), P (F / S) and P (F / N)?

b. Calculate the probability of a random flight being delayed

c. Find the probability of a random flight being delayed and SAS aircraft

d. Calculate the probability that a random flight in flight is a Norwegian flight
