Answer 1

B. Configuration B has a higher probability of an aisle seat.

Explanation:

Each configuration has the same number of seats in every row. That means we can determine the probability Dan will be assigned an aisle seat by considering only one row.

In configuration A, each row has 6 seats, of which 2 are aisle seats. The probability of being assigned an aisle seat is ...

p(aisle) = 2/6 = 1/3 . . . . configuration A

In configuration B, each row has 9 seats, of which 4 are aisle seats. The probability of being assigned an aisle seat is ...

p(aisle) = 4/9

Since 4/9 > 1/3, Dan should hope his flight uses configuration B.
