So in this problem, we're told that we have a standard deck of 52 cards, and we want to figure out the probability for each situation.
00:06
So in part a, we want to figure out the probability that we would pull a queen.
00:11
Well, remember, there's a queen in each suit of our deck, so it means that there's four total queens in the deck.
00:17
So there's four ways to pull a queen, divided by the total number of ways, which is 52.
00:22
And typically, a probability always reduce.
00:24
So if we divide the numerator denominator by four, that will leave us with 1 over 13.
00:28
So that's the probability of pulling your queen.
00:32
Okay.
00:32
Now, for part b, we want to determine the probability that we're going to get an ace or a 10.
00:40
So the first thing we have to do is figure out how many aces or tens are in the deck.
00:44
Well, again, every suit is going to have an ace and every suit is going to have a 10.
00:49
So because there's four suits in the deck, that means there's going to be a total of eight choices between the aces and tens.
00:56
So that will be our numerator.
00:57
And our denominator is still 52 because, again, there's 52 cards in the death...
