Cynthia picks a card out of a deck of 52. She puts it back. Charles picks a card from the same deck. What is the probability that they both picked the Queen of Hearts?
The probability of picking the queen of hearts is 1/52. To pick this again would again be a 1/52 chance. To figure out the chance of both of these happening, you multiply the probabilities. Remember: If it's something AND something else, you MULTIPLY. If it's something OR something else, you ADD.
it wouldn't matter because taking a card and putting it back is a form of cheating...
lol
haha, thank you.
@Crowley why it is 1/52? ? as it says "Queen Of Hearts" ?
Because you're figuring out the probability of picking ONE specific card out of a full deck of 52, making it a one in fifty-two chance, hence 1/52.
Ok)
1/52*1/52
