Okay, so for this problem, what we're doing is trying to find the probability that we're going to have five cards in a row, not all the same suit.
00:08
So what we want to do is we want to think about this.
00:12
So if we need five cards in a row, ace could be high or low.
00:15
That means we're going to need to have a card somewhere between an ace and a 10.
00:19
So we know that there are 10 cards total, and there's four different suits.
00:24
So that's going to be a total of 40.
00:27
And then what we know is that obviously the first card, we're going to have 40 choices.
00:33
Then the second card, we're going to have four, because it's going to be either the next card, higher or lower.
00:39
There's going to be four different possibilities...
