So if you're dealt a four cards from a shuffle deck of 52 cards, find them probably getting one queen and three kings.
00:08
So let's start with the total number of four hands, four card hands, i should say.
00:15
And so i'm going to find that by you doing a combination here.
00:18
The order doesn't matter so we can do out of 52 cards, we are choosing four options.
00:24
So if i plug that in my calculator, do a combination like that.
00:26
I get 270 ,725.
00:33
So now we want to look at this.
00:36
If we're looking at the probability of getting one queen and three kings, we need to look at the total possibilities of each of them.
00:44
So for example, for one queen, there are four possibilities, and we're choosing one of them.
00:49
So if i do that, i do four combination one.
00:51
There is four possibilities...
