What is the probability of drawing three red cards, one at a time without replacement, from a standard deck of 52 cards?

Answer 1

How many red cards are there in a standard deck of 52 cards?

Answer 2

three

Answer 3

Nono. How many red cards are there in TOTAL in a standard deck of 52 cards. :)

Answer 4

26

Answer 5

Good. So the probability of getting ONE red card is 1/2. Correct, or do you disagree?

Answer 6

yes,but that's not an answer choice.

Answer 7

Do you know how to calculate the probability of picking ONE red card from a deck? If you do, then apply that logic to calculate the probability of picking three cards, one by one, and each time the total number of cards decreases by 1, as does the total number of red cards.

Answer 8

I know.

Answer 9

So. The probability of finding one red card is 1/2. After you got your red card on your first try, then what is the probability of finding a red card, if you didn't replace the red card?

Answer 10

HINT: How many red cards are there in the standard deck now?

Answer 11

2/51

Answer 12

Well. How many red cards are there in the total deck?

Answer 13

26

Answer 14

Nope. We took one red card out. So how many red cards do we have now?

Answer 15

25

Answer 16

Great! Also, the total amount of cards has decreased by 1. So how many cards are there in total now?

Answer 17

51

Answer 18

Good. So the probability of getting another red card is 25/51. Make sense so far?

Answer 19

yes, but I don't see that as a choice.

Answer 20

We're not finish. :)
That was the probabiltiy of finding the second red card.
Wht do you think is the probability of finding the third red card when we took out the second red card?

Answer 21

24/50

Answer 22

Good.
So the probability of finding a third red card is 24/50. Now I believe you would multiply the 3 fractions. What would that give us?

Answer 23

um, I got 1/22100. that can't be right

Answer 24

Are you sure you multiply right? What did you multiply?

Answer 25

everything

Answer 26

Show ,e the fraction that you multiply.

Answer 27

3/52*2/51*1/50

Answer 28

Where did you get that fraction?

Answer 29

Waht is the probability of getting one red card?

Answer 30

1/50 I thought

Answer 31

Nooo!! Scroll up, I corrected your mistake.

Answer 32

24/50

Answer 33

multiply by?

Answer 34

26/52*25/51*24/50 and I got 2/17

Answer 35

Are you sure? Lets simplify the fraction.
You know what (24/50) simplify to?

Answer 36

2/17 is correct

Answer 37

What's the answer choices?

Answer 38

If its around 2/17, then it is correct.
