Hi, i'm david and i have you answer your question.
00:03
Now let me bring up your question here.
00:07
In the question here we are going to play card and we have the deck under 52 cards and we want to draw one card randomly from the deck and we'll compute the probability in the question a, b and c.
00:23
Now to help us answer this question easily, i will bring up the outcomes under 52 card.
00:28
And put the outcomes on the right here.
00:38
So that will be the totally 52 card we have on the deck.
00:43
And in the question a, once you find the probability that we have the number 3 or the number 9.
00:52
So we see we have the number 3, we have 4 of them, and then the number 9 also 4 of them.
01:03
So therefore the probability that equal to the proportion.
01:06
The denominator will be the total 52 card...
