Question

Check my answer
If you have a deck of cards if you had to pick a red one and a black one what is the probability?
52/26 26 divided by 26 = 0 red ones
52/26 26 divided by 26 = 0 Black ones
so is the probability is 0

Answer 1

yes. because you cannot have a red one and a black one at the same time.

Answer 2

? A redone followed by a black one?

Answer 3

estudier, what do you mean by your answer

Answer 4

marktierra, so I did it right because I put it into my study group and someone told me it was wrong?

Answer 5

estudier wants you to better define the question.

Answer 6

are you spose to pick only one card that is both red and black?

or pick 2 cards such that you get a red one then a black one?

Answer 7

That's right, I didn't really understand the question.....

Answer 8

if 2 cards; then th eprob of getting a red one is 1/2 ; 26/52

the odds of pulling a black one next is reduced then to; 26/51 given that you pull a red one first

the sum of those would amount to the prob of getting a red then a black card

Answer 9

One card is selected at random from a deck of cards. determine the probability that the card selected is a red card and a black card

Answer 10

since a card is either red OR black; the prob that a card is red AND black is 0

Answer 11

Right, no calculations required......:-)
