Just cant seem to completely wrap my head around some problems involving combinatorics. Here's a question that I think uses combinations and that kind of stuff

There are 10 distinct items to choose from. You pick 6 of the items at random. Another person chooses 8 items at random (after they have all been put back obviously). what is the probability that you picked 3 items in common?

I kind of made this one up, but it's along the lines of the problems that I sometimes struggle with. Does this even require the use of combinations? And if you have any tips for handling these kinds of problems that would be great.

thanks!
