• #deepak right ans is 13/18. option (b)
  at least 2 men throw same no = 1-none of them throw same no
  =1-(6/6+5/6+4/6+3/6)
  =1-5/18=13/18 ans

• I think its 252 but not confirmed.
  
  Method used: 10!/(5!*5!) =252

• ans 13/18
  probability of not getting same no
  1st person:6/6
  2nd person:5/6
  3 : 4/6
  4: 3/6
  probability of not getting similar is 6/6*5/6*4/6*3/6=5/18
  probabilty of getting is:1-5/18=13/18 (ans)
