Total chance comes to 3/24 * 2/23 * 1/22 or (3*2*1)/(24*23*22) = 6/12144 = 1/2024 or just under 0.05 %
Calculating the chance of drawing three of the five seats next to Daisuke if there are 30 seats total is left as an excercise for the reader!

Let's throw some maths at this problem. If there are 25 seats, and Daisuke is already occupying one of them, that means the chance of drawing one of the three seats next to him is 3/24. Since two seats are now taken, then for the next seat the chance will be 2/23, and for the third 1/22.assuming there's 25 seats, what are the odds that all 3 of them would score that particular place? do we just 24% 3 times
