There are two vessels P and Q, containing only milk and only water respectively. The volume of milk in P is the same as the volume of water in Q. Now one-third the contents of P are poured into Q, after which one-fourth the contents of Q are poured back into P. If this process is repeated 15 more times, what is the approximate final concentration of milk in vessel P?
33.33%

Distributing 3 similar chocolates among two people --> a+b = 3 --> 4c1 = 4 ways
Distributing 3 different chocolates among two people ---> 2 x 2 x 2 = 8 ways ?
Distributing 3 different chocolates among two people. Is this similar to binomial expansion and equal to 3c0 + 3c1 + 3c2 + 3c3 = 2^3 = 8 ways?
I am a little confused about these things. Can anyone clarify and throw some light on the matter.
