If the word MONOS is permuted then the probability that O’s never come
together?

• POOJAMALI is correct...
  
  Total permutations by MONOS = 5!/2!=120/2=60
  If O's comes together then with M,N,OO,S we can form 4!=24 words
  So the words with O's never come together are =total- O's comes together
  =60-24=36
  so probability of O's never come together=36/60=3/5...

• Total combination=5!/2!(because o is repeating).
  and now combination if we combine os and so never come together=(5!/2!)-(4!*2!)
  ans is 1/5.

• is 3/5 is right ans by calculating the 60-4!/60

• total MONOS so 5!=120
  O come together (OO)MNS so 4!=24
  (00) 2!/2!== 1
  so 24*1=24
  prob 24/120==1/5
  but OOnever come tgr so prob 1-(1/5) =4/5

• ((5!/2!)-4!)/(5!/2!)
• 12 years agoHelpfull: Yes(3) No(9)
• 1-(4!*2!/5!)=3/5

• if o always come together than permutation=4!=24
  total permutaion of arranging the word is=5!/2=60
  so if o never come together =60-24=36
  so probability of never come together=36/60=3/5
  option (D) is correct
