A consumer agency randomly selected 1700 flights for two major airlines, A and B. The following table gives the two-way classification of these flights based on airline and arrival time. €œless than 30 minutes late€ includes flights that arrived early or on time.

a. Suppose one flight is selected at random from these 1700 flights. Find the following probabilities.
i. P(more than 1 hour late and airline A)
ii. P(airline B and less than 30 minutes late)
b. Find the joint probability of events €œ30 minutes to 1 hour late€ and €œmore than 1 hour late.€ Is this probability zero? Explain why or why not.
