3 letters from the alphabet are chosen at random. What is the probability that one of those letters would be X. the letters may be used more than once.
Thanks

So, we have three draws of one from a population of 26, with replacement.

Great.

What's p(drawing an X) on one draw?
Are successive draws independent?
