Hey there, welcome to numerade.
00:02
We have a standard 52 card deck over here where we are asked to find the chances where the card is replaced and the deck is reshuffled.
00:15
So we're going to start with number one here.
00:21
What are the chances of drawing a club or a red card on the second draw? so what we have here? is the probability of drawing a club or a red card.
00:45
So what we have to think of is how many clubs are there in a deck? so what we know here is that there are, which is 13 plus how many red cards are there in a deck? we have exactly half, so it will be 26 over, 52.
01:13
So 13 plus 26 equals 39 divided by 52.
01:24
So let's see what that equals.
01:28
We have 39 divided by 52, equaling exactly 0 .75.
01:39
Okay.
01:41
So with this here, we have our number two.
01:46
So since we are looking at so we draw the first club and the deck is reshuffle and replaced.
02:01
So therefore the card is going to be replaced here...
