6.30. Two different airlines have a flight from Los Angeles to New York that departs each weekday morning at a certain time. Let E denote the event that the first airline's flight is fully booked on a particular day, and let F denote the event that the second airline's flight is fully booked on that same day. Suppose that P(E) = .7, P(F) = .6, and P(EN F) = .54. a. Calculate P(E\F), the probability that the first airline's flight is fully booked given that the second airline's flight is fully booked. (Hint: See Example 6.12.) b. Calculate P(E|F).

Question
**Exercise 6.30: Probability Analysis of Flight Bookings**

Two different airlines offer a flight from Los Angeles to New York that departs each weekday morning at the same scheduled time. Define event \( E \) as the occurrence of the first airline's flight being fully booked on a specific day, and event \( F \) as the occurrence of the second airline's flight being fully booked on the same day.

Given the probabilities:
- \( P(E) = 0.7 \)
- \( P(F) = 0.6 \)
- \( P(E \cap F) = 0.54 \)

**Tasks:**

a. Calculate \( P(E|F) \), the conditional probability that the first airline's flight is fully booked given that the second airline's flight is fully booked. (Hint: Refer to Example 6.12 for guidance.)

b. Calculate \( P(F|E) \), the conditional probability that the second airline’s flight is fully booked given that the first airline’s flight is fully booked. 

Consider using the formula for conditional probability:
\[ P(E|F) = \frac{P(E \cap F)}{P(F)} \]
\[ P(F|E) = \frac{P(E \cap F)}{P(E)} \]
