How to solve this???
Two couples and one single person are seated at random in a row of five chairs. What is the probability that neither of the couples sits together in adjacent chairs?
a)1/5
b)1/4
c)3/8
d)2/5
e)1/2
I am having problems in Probability .Especially when to choose P or choose C(Permutations formula or Combination Formula).
Would be thankful if any stalwart can help me and guide me for probability.
