• A fair coin is tossed three times. What is the probability of getting exactly two heads?
• Which formula correctly defines the conditional probability of A given B, assuming P(B) > 0?
• What is the expected value of the number shown on a fair six-sided die?
• Events A and B are independent, with P(A) = 0.6 and P(B) = 0.3. What is P(A ∩ B)?
• Match each probability concept with its correct description.
• Match each probability distribution with the situation it models most directly.
• Match each notation with its standard probability meaning.
• Match each scenario with its most appropriate probability method.
