The probability of drawing three red cards from a standard deck of 52 cards?

OpenStudy (xapproachesinfinity):

the probability of cards, i don't like it haha since i don't play this cards game lol so i always confuse some cards so how many cards are red in a deck of 52

OpenStudy (solomonzelman):

1/4 of the cards is red

OpenStudy (solomonzelman):

I mean 1/2

OpenStudy (xapproachesinfinity):

4 hearts, 4...

OpenStudy (xapproachesinfinity):

i believe 4 kinds are red? no?

OpenStudy (anonymous):

what do you mean?

OpenStudy (anonymous):

i meant what is the probability

OpenStudy (xapproachesinfinity):

he said it is 1/2

OpenStudy (anonymous):

i dont have that choice thouggh

OpenStudy (anonymous):

so therefore he is not right

OpenStudy (anonymous):

i have choices a.3/52 b.2/17 c.1/8 d.75/676

OpenStudy (xapproachesinfinity):

do like this @SolomonZelman haha

OpenStudy (xapproachesinfinity):

as i said don't remember all the cards

OpenStudy (anonymous):

well nevermind then

OpenStudy (anonymous):

There are 13 cards per suit. Two suits are red. Therefor, there are 26 red cards in the deck.

OpenStudy (anonymous):

I've got no Idea for the rest of the problem. Just thought I'd throw that out there.

OpenStudy (xapproachesinfinity):

3 out of 26

OpenStudy (xapproachesinfinity):

@ikram002p check here.

OpenStudy (ikram002p):

two groups have red color in 52 so 26 card from 52 is red , hence probability of one card is 1/2 now for 3 its (1/2)^3 1/8 i hope this is correct :o

OpenStudy (ikram002p):

typo* now for 3 its (1/2)^3= 1/8

OpenStudy (xapproachesinfinity):

@ikram002p yeah that's correct!

OpenStudy (ikram002p):
