Probability question..... (1 Viewer)

[16021991]

Hi Everyone I have another probelm (it was bound to happen). A past paper question that is: One card is drawn from a pack of cards and kept on the table. A second is drawn and placed next to it. What is the probability the second card is from a different suit to the first? I would have said 52/52 x 39/51. But Success One says its 52/53 x 39/51........ can anyone explain this?? Thanks guys!!!

You forgot the joker. No lol, i'm pretty sure it's a typo i was thinking the same thing. Makes no sense doing 52/53 when there are only 52 cards in a standard deck.

Really, are you sure? I just wouldn't have thought that Success One would have a typo...

Would be a typo. I know of 1 question SuccessOne has wrong, so I wouldn't be surprised if theres more.
