Medal and Become Fan Rewarded for Correct Information/Answer... Please help me :D Find the odds. The kings are separated from a deck of standard playing cards and shuffled. One king is randomly selected. What are the odds in favor of drawing a black card? A. 4 to 1 B. 1 to 4 C. 1 to 2 D. 1 to 1
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?
No. What is the probability of drawing a black card?
Can you please bear with me while I take you through the steps. There are 4 cards, 2 of which are black. So what is the probability of drawing a black card?
There are 2 ways you can draw a black king from the 4 possibilities. 2/4 = 1/2 = 50%
Good work! You are correct. There are 4 cards, 2 of which are not black. So what is the probability of drawing a card that is not black?
thx but i'm still a little confused..I dont know why :(
Can you just answer this and then the final answer will soon emerge: There are 4 cards, 2 of which are not black. So what is the probability of drawing a card that is not black?
Do you think that the probabilities of drawing a card that is black and a card that is not black are the same?
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?
You are correct! Well done :)
