Bro P(N,2) is what i Did.
P(N,2) = N!/(n-2)! = N*(N-1) .
I think Answer given is wrong. It Shud be 1/(N-1)

Number of cases : N * (N-1)Â˛
Required Cases : [N* (N-1)]
Hence Prob : { [N* (N-1)] / N*(N-1)Â˛ } = 1/ (N-1)

54^124 = 3^124 Mod 17 , Now Since HCF(3,17) = 1 We can apply Euler
3^8 = -1 Mod 17 , which gives (3^8)^15 * 3^4 = -1 * 13 = -13 or 4 Mod 17 ;)
