Socks in a bag.......

Just wanted to know if I have the correct answer to the following problem:

You have a bag of 3 black, 3 blue and 2 white socks. Suppose you reach in without looking and pull out a sock. How many times must you reach into the bag to be certain to get two socks the same color?

My answer was 4- because there are three different colors and if you only pull out three or less, you could end up with different socks. However, if you pull out 4 socks, you will get at least one matching pair.

Thanks for the help!!

You are correct.

Thank you very much!!
