00:01
So we can have nine players playing baseball.
00:04
And we want to know in part a, what's the likelihood that fred, mike, or jason, so fred or mike, or jason, and let's call that event a.
00:23
We want to know what's the probability of one of those three being chosen as pitcher.
00:29
And that ends up being a three out of nine chance or a one -third chance of that happening.
00:36
Now our next event is b that after a happens then b would be that sam or paul end up being chosen to be i believe it was first base and so we want to find the probability of a happening and then b happening and so we know it's a one out of three chance of the first one happening now one of our or a three out of nine chance now one of our players is no longer available because it is he has been chosen to be the pitcher.
01:11
So there are eight players left of which two of them are the sam and paul.
01:16
And so this becomes one third times one fourth, which is a one -twelfth chance.
01:22
Now on part c, we want to have a happen and then b happen.
01:29
And then we want bob to be the catcher...
