Questions 1. In Part 1, what was the expected ratio of heads to tails for tosses of a single coin? Did your results always agree with the expected ratio? If not, what would be a reason for the deviation? 50/50. No. 2. Compare the deviations from the expected for 20, 30, 50 and 100 tosses. What seems to be the relationship between the sample size and deviation? 3. In Part II, what was the probability that tails would appear on both coins? How did you arrive. at this answer?
