AI explanation

The probability of a future event for an unfair coin is determined solely by its established bias, not by the frequency of past outcomes. The empirical probability of landing on heads is calculated by dividing the 14 successful heads by the 20 total tosses, resulting in 0.7. Therefore, the probability of the coin landing on heads on the 21st toss remains 0.7.
