Answer the question.How would you find the empirical probability of getting a red card, if you are choosing a card from an ordinary deck of 52 cards?
A. Choose a card from a deck of 52 cards 52 times and then find the relative frequency of red cards. This would be done by dividing the number of times a red card has occurred by 52. B. Choose a card from a deck of 52 cards 2 times and then find the relative frequency of red cards. This would be done by dividing the number of times a red card has occurred by 2. C. Choose a card from a deck of 52 cards many times and then find the relative frequency of red cards. This would be done by dividing the number of times a red card has occurred by the total number of times a card was chosen. D. The empirical probability cannot be determined.
