Suppose that three cards are drawn from a well -shuffled deck of 52 cards.
00:05
What is the probability that they are all aces? okay, so the probability setup that we can think of is it's going to be the number of ways to get a success divided by number of total ways.
00:27
That's how we can set up the ratio or the fractional probability of most things.
00:31
So if we're talking about a deck of 52 cards, hopefully we know that there are four total aces in a deck of 52 cards.
00:39
So what that means is if i want the probability of an ace, that's the notation we can use, there are four ways that that can happen out of our 52 total cards.
00:49
Now for our second ace, probability of another ace, multiple events indicates that we would multiply these things together because we're doing three things in a row.
01:00
There's only three aces left because that first one has already been drawn and there's only 51 cards left in the deck of cards.
01:13
So following that logic, three out of 51 would be our second probability...
