• 23c2=23*22/2=252
• 14 years agoHelpfull: Yes(4) No(36)
• ans is 22.
  for cyclic use (n-1)
  for non-cyclic use nC2.

• 253 Handshakes are possible. for one shake we need two hands. so 23C2=253.

• cmplete no of handshakes with repetition = sigma22
  (1st person with 22 , 2nd with 21 so on...)
  22(22+1)/2
  =252
