There are 4 kings in a standard pack. Two of the 4 kings are in black suits. The odds are the ratio of the probability of drawing a black card to the probability of not drawing a black card. Can you see what the correct choice is?

There are 2 ways you can draw a black king from the 4 possibilities. 2/4 = 1/2 = 50%

Do you think that the probabilities of drawing a card that is black and a card that is not black are the same?

1 to 2

The odds are the ratio of the probability of drawing a black card to the probability of not drawing a black card. The two probabilities are equal in this case. Can you now see what the correct choice of the odds must be?
