How many cards mush you draw from a deck of 52 playing cards to be sure tat at least two are from the same suit?

how would you work this out??

would it be...

you must draw at least 12 cards to get at least 2 from the same suit?

To find out how many cards you must draw from a deck of 52 playing cards to be sure that at least two of them are from the same suit, you need to consider the worst-case scenario. In this case, you want to make sure that all four suits are covered.

The largest number of cards you can pick from each suit without getting a matching pair is 13 (since there are 13 cards in each suit). So, for the first card, you can pick any of the 52 cards. For the second card, you want to avoid picking a card of the same suit as the first one. Therefore, you need to avoid picking all 13 cards of that suit.

To ensure you don't get a matching pair, you would need to pick one card from each of the remaining three suits. The maximum number of cards you can choose from each of the remaining suits (assuming you haven't picked any cards of those suits yet) is also 13.

So, you would need to pick 13 + 13 + 13 + 1 cards to be sure that at least two cards are from the same suit. This totals to 40.

Therefore, you must draw at least 40 cards from a deck of 52 playing cards to be certain that at least two cards are from the same suit.

It is a percentage. There are 52 cards in a deck. There are 13 cards in each suit. I think you can do the rest.
