how do i go by solving this

cwrw238 · Answer

Hint: there are 13 clubs in a pack of cards

anonymous · Answer

so by that information i eliminate B and C

cwrw238 · Answer

- so you do not have to consider the whole pack

cwrw238 · Answer

yes

anonymous · Answer

so most likely i would go with D

cwrw238 · Answer

yes D is correct

anonymous · Answer

even though theres 13 theres 54 cards in a entire deck

cwrw238 · Answer

there is only one queen in the 13 clubs

cwrw238 · Answer

yes - you only consider the 13 clubs - thats given in the question

cwrw238 · Answer

its called conditional probability

anonymous · Answer

Is D really correct?

anonymous · Answer

wow i see thank you so very much more so explained that way it makes more sense @cwrw238

anonymous · Answer

Because it says "What is the probability that the card is a queen, given that the card is a club?" I think It's supposed to be a queen and a club. @cwrw238

anonymous · Answer

And there is only 1 card that is a queen and club, so wouldn't the answer be B?

anonymous · Answer

yeas given that there is rarely a chance of it being a question out of 13 most likely it would be 1

anonymous · Answer

@cwrw238  Hmm?

cwrw238 · Answer

well - i know its a long time since I did this stuff but I think I'm right.

anonymous · Answer

Okay... o.o
