Answer the question.How you would find the empirical probability of rolling a 5 on a die?
A. Roll a die 6 times and then find the relative frequency of rolling a 5. The relative frequency would be obtained by dividing the number of times a 5 has occurred by 6. B. Roll a die many times and then find the relative frequency of rolling a 5. The relative frequency would be obtained by dividing the number of times a 5 has occurred by the total number of times the die was tossed. C. Roll a die 1 time and then find the relative frequency of rolling a 5. The relative frequency would be obtained by dividing the number of times a 5 has occurred by 1. D. The empirical probability cannot be determined.
