Okay, so a 'fair coin' means it's truly 50/50, no trickery. It's good they're setting that clear expectation about equal chances from the start.
Got it, heads on one side, tails on the other, with George Washington on the quarter. Simple visuals to make the concept relatable.

Probability is introduced as a measure of the likelihood of random events. The foundational concept, illustrated with a fair coin flip [0:24], defines probability as the ratio of favorable outcomes to the total number of equally likely possibilities [1:39]. For instance, the chance of getting heads on a coin flip is 1/2 [2:29], or 50%, because there are two equally likely outcomes (heads or tails) and only one desired outcome (heads) [2:04]. This can also be understood by envisioning the experiment performed an infinite number of times, where approximately 50% of the flips would result in heads [3:19].
