I got lost with simple probability question.
There are three varaeties of candies in a can.
Three candies are selected randomly.
What is the probability that all of them are of the same kind?
It seems to be [itex]1\frac{1}{3}\frac{1}{3}=\frac{1}{9}[/itex]
But at the same time we can calculate it as [itex]\frac{C^1_3}{C^3_{3+3-1}}=\frac{3}{10}[/itex]
What is the right answer here?
