Suppose there are only 2 people.
P(me getting my seat)= P(steve sitting on his seat)=0.5
if there are 3 people
P(me getting my seat)=P(steve sitting on his seat)+P(steve sitting on wrong seat)*P(another person sitting on his seat)
=(1/3)+(2/3)*(1/2)=2/3
similarly if its 4 seats =3/4
P(n=100)=99/100- 75578 views
