Hey there, welcome to numerade.
00:03
We are selecting three cards from an ordinary playing deck, and we ask what is the probability of drawing 150 cards as an ace, another one as a 10 or a jack, and the last one here as a queen or a king.
00:18
So what we know here, the probability of drawing an ace, so a for ace, we have four aces in a standard 52 deck.
00:30
So we have 4 out of 52.
00:34
And for our probability, for a 10 or a jack, 10 or jack, the probability here would be then the remaining 8, because we have 4 tens and 4 jacks out of 51.
00:52
And our third card over here, which is basically a queen or a king, is also represented as 8 for the numerator because we're not.
01:04
We have four queens and four kings, but it's going to be out of 50 since we drew two already...
