Answer:

1/20

Step-by-step explanation:

The probability of any of the friends sitting on any of the seats is equal.

So the probability of Hamad sitting on the first seat = 1/5

As Hamad is sat on the first seat, there are now 4 available seats, so the probability of Riyadh sitting on the second seat = 1/4

Therefore, probability of Hamad sitting on the first seat AND Riyadh sitting on the second seat = 1/5 x 1/4 = 1/20
