This problem deals with a standard 52 card deck, and of those 52 cards, you've got 13 diamonds, 13 hearts, 13 clubs, and 13 spades.

All right, so a says, what is the smallest number of cards that we would need to take from the deck to guarantee that we will have at least seven cards with the same suit? now, you know, you may be thinking the least number, and you may be thinking, okay, well, i'm gonna get all seven of them the first time.
00:46
That's not a guarantee.

We're talking about what's the smallest number that you can guarantee to have at least seven of the same, suit.

So, what if you draw six diamonds, and six hearts, and six clubs, and six spades? you don't have seven of the same suit, but the very next card i draw will be one of those.
01:24
So, in order to guarantee that i have seven from the same suit, i have to draw 25 cards.
01:35
Now, i'm not saying that you have to draw 25 cards to get it.

You could get the first seven to be all seven the same, but i'm talking about to guarantee that you have seven of the same, you would have to draw 25 cards...
