Should have listened to Mertsj

Answer 11

But you said there are 52 cards not 39, right man?

Answer 12

So everyone agrees the answer is False?

Answer 13

Sorry, I was reading that as probability, not odds. I agree.

Answer 14

You need to convince yourself.

Answer 15

NO. The answer is true. The answer is 13/39 or 1/3 or 1 to 3

Answer 16

The probability of getting a heart is 13/52
The odds are 13/39

Answer 17

If p is the probability of the win, and 1-p is the probability of the loss, the odds are \[\frac{p}{1-p}\] so here it would be .25/.75 or 1:3 which is equivalent to 13:39.

Answer 18

I see.... so the correct answer is true

Answer 19

Yes, sorry for misreading the question. I suspect that such questions on the SAT or GRE snare more than a few victims!
