We are required to find In how many ways can they finish in first and second place

We will use combination over here

\

Now out of 25 , 1 got the first place

So, n =25

r =1

Now since first place is occupied so for second place there are 24 people

So, n = 24

r = 1

So, no. of ways they can finish in first and second place =

                                                                                             =

                                                                                             =
