How do I calculate the probability of getting a flush from a 52 card deck using mathematica?

I know how to calculate this with pen and paper but would like to do the same in mathematica. However I’m new to mathematica so I have no idea where I’m supposed to start. Watched a couple of YouTube videos but none explain how I can calculate the probability of getting a flush from 52 cards by searching through each 5 card combination. The flush should be determined using the three community cards and two holecards just like in Texas hold em.
