In a hand of poker, five cards are dealt from a regular pack of 52 cards.
00:05
And how many of these hands are there in each category? i don't really like the wording of that, but let's say, let's look at this as probability.
00:14
What's the probability of getting four kings? so the four kings are going to be four times three times two times one.
00:25
Then we're going to have 48 remaining cards and we need to pick one from that.
00:30
And that will be out of 15.
00:34
With scars 15 52 combination 5 so that gives us 1 ,152 over 2 million 598 ,960 which is roughly 0 .004 for the probability of two clubs and three hearts there are 13 combination two for the clubs 3 for the hearts divided by 52 combination 5.
01:12
So that gives us 22 ,308 divided by 2 ,598 ,960, which is 0 .0086.
01:23
For c, what if they're all hearts? so there are 13 times 12 times 11 times 10 times 9.
01:32
We could also say 13 combination 5 divided by 15 combination 5...
