This is an activity-based question, so the answers for (i) and (ii) will vary based on the actual experiment. Assuming a sample outcome of 12 heads and 8 tails out of 20 tosses, we calculate the experimental probability for (iii). For part (iv), the context highlights the Gambler's Fallacy, emphasizing that a coin has no memory of past flips, so the probability of getting tails on the next toss remains exactly the same as before, which is 1/2.
