"Pick a card, any card" probability question

Let's suppose you are a magician. However, you do not know how to do the "pick a card, any card" trick. At the end of each game you play, you just take a random card out and hope and pray that it matches the one the person picked. Is the probability that you chose the right card 1/52 for a 52 card deck??? Does this mean that you are probably gonna get it right one out of 52 games that you play???

Re: "Pick a card, any card" probability question

You will get it right on the average of 1 in 52 tries. The probability of getting it right at least once in 52 tries is 1 - (51/52)^52 ~ 0.63.
