Okay, i copied your question and pasted it on here so we can look at it as we go.
00:04
So you have 52 cards in a deck.
00:06
Find the following condition of probability.
00:10
The card is a club given that it is black.
00:14
So there are 26 black cards.
00:17
So first let's say there are hearts.
00:24
There are 13 hearts.
00:26
There are spades.
00:29
There's 13 of those.
00:31
There are clubs.
00:34
And there's 13 clubs.
00:36
And there are diamonds, and there's 13 of those.
00:43
So given that they, you know it's black, for it to be black, it's either a club or a spade.
00:50
So there's 26.
00:51
Out of those 26, for it to be a club, there's 13 possibilities.
00:56
So that is one half.
00:59
So this one is one half.
01:06
The next one says that, that is black given that it is a club...
