Probability Rules and Expected Values

🎬 Video Tutorial

(0:01) Equiprobable Events: Events with equal chances of occurring. For example, a fair six-sided die, each face has a probability of $\large \frac{1}{6}$ of landing face-up.
(1:32) Addition Rule for Probability: For mutually exclusive events (events that can’t occur simultaneously), the probability of $A$ or $B$ is the sum of their probabilities. E.g., $P$(Blue or Red) = $P$(Blue) + $P$(Red).
(2:23) Understanding Expected Frequency: Expected values are estimations; actual outcomes may vary.
