Joshua is conducting an experiment and calculating the experimental probability of flipping a coin and landing on heads. Which amount of times should Joshua flip the coin so that his experimental probability is closest to the theoretical?
A) 2 B) 10 C) 30 D) 300
What is D - 300
*Remember, you always want to do it the most times. The more times you conduct an experiment, the closer your probabilities will be.
What type of correlation is shown?
