Quiz1t Probable QuestionS If evens A and B are mutually exclusive what is the probability of their INTERSECTION? o the probability of intersection of two events, A & B, is 0 (zero) since mutually exclusive refers to events that do not have any common outcome. 5/5 o If evens A and B are independent what is the probability of their INTERSECTION? o P(AnB) = P(A) P(B) it is the product of the two independent events 5/5 If evens A and B are mutually exclusive what is the probability of their UNION? If events A and B are not independent. What is the probability of their UNION? o The probability equation to use is: P(AnB)=P(A)P(B) for independence. Since events A and B are not independent, then the probability of their Union is 0. 2/5 Graders comments: =P(A) + P(B) - P(AB) o The probability equation for independent is P[AB] = P[A] P[B]. Since A and B are not independent then the probability of their union is zero. But if the event A and B are P[AB]= P[A] + P[B] then the probability is gt zero.

Therefore, out of all six possibilities, their possibility of showing up would be 2/6. answer: 2/6 5/5 o each face has a probability of 1/6. 4 - 1/6 5 - 1/6 6 - 1/6 These probabilities add up to 3/6 or 1/2. 5/5 • Find the probability that a single toss of a fair die will result in the number 4 or less if it is given that the toss resulted in an even number. • Find the probability that a single toss of a fair die will result in the number 3 or less if it is given that the toss resulted in an even number....
