This problem tells us a basket contains six apples, four pears, and three oranges.
00:04
If two are picked at random, what is the probability that both are pairs? so first we need to know the total amount of fruit that's in this basket.
00:11
So six plus four plus three gives us 13 total.
00:15
And since we're picking two fruits or two at random, that's going to be two events that we need to happen.
00:21
We need the first and the second fruit that we pull out to be pairs.
00:25
And since we're not specifically told that once we pick one out, we put it back, we have to take into account the results of the first fruit being what we want when we look at the probability of the second fruit.
00:35
So first with the first fruit, if we don't know the probability that that one specific fruit is a pair, we have four pairs out of the 13 total options.
00:44
So a four and 13 chance, or that's the probability of the first one being a pair.
00:48
If we want to know the probability that the second one is also a pair, again, we need to take into account that we're not replacing the fruit after we take it out...
