Step-by-step explanation:

Answer 2

The word expected has a very exact meaning in probability theory which is perhaps not what you meant. However in case you meant that each experiment consisted of tossing 8 two sided fair coins and by frequency you mean the fraction of times you get k heads and 8 minus k tails the expected value is 8 choose k times 1/256. This is just the binomial distribution for probability 1/2. The number of times you do the experiment has no bearing on the expected value only the variance because the expected value is calculated based on what happens if the number of experiments goes to infinity
