We remove the 18 regular customers and their seats from consideration.

Thus, we consider the 23 - 18 remaining customers = 5; and 19 - 18 = 1 seat.

Overbooking means 3 or more of the 5 remaining passengers; each has a 50% chance remaining.

Overbooking = 1 - P(X ≤ 2) = 0.5

Probability of empty seats = P(X ≤ 1) = 0.1875

Jadi jumlah derajat tidak masalah. Mereka masih akan menempuh jarak yang sama.

Karena Anda mengatakan bahwa ekspres Marina berjalan pada 40 km / jam dan kami melakukan 2 jam. 40 * 2 = 80 km. Untuk Dumai Anda melakukan hal yang sama, 48 * 2 = 96.

Marina berjalan sejauh 80 km

Dumai berjarak 96 km
