## Multiple Choice Questions ### Question 1 **Question Type:** multiple\_choice **Question Text:** What is the range of possible values for the probability of an event? **Answer A:** -1 to 1 **Answer B:** 0 to 100 **Answer C:** 0 to 1 **Answer D:** 100 to 100 **Correct Answers:** C **CorrectAnswerText:** The probability of an event is between 0 (impossible) and 1 (certain). ### Question 2 **Question Type:** multiple\_choice **Question Text:** What is a sample space? **Answer A:** An event that cannot occur **Answer B:** The sum of the probabilities of all the events **Answer C:** The set of all possible outcomes of a random process **Answer D:** The probability of a specific event **Correct Answers:** C **CorrectAnswerText:** The sample space is defined as the set of all possible outcomes of a random process. ### Question 3 **Question Type:** multiple\_choice **Question Text:** How do you calculate the probability of an event? **Answer A:** Divide the number of favorable outcomes by the total number of possible outcomes **Answer B:** Add the favorable outcomes to the total of outcomes **Answer C:** Subtract the possible outcomes from the favorable outcomes **Answer D:** Multiply the number of favorable outcomes by the total number of outcomes **Correct Answers:** A **CorrectAnswerText:** The probability of any event is calculated by dividing the number of favorable outcomes by the total possible outcomes. ### Question 4 **Question Type:** multiple\_choice **Question Text:** Which statement describes mutually exclusive events? **Answer A:** Events whose probabilities are independent **Answer B:** Events that include all possible outcomes **Answer C:** Events that can happen at the same time **Answer D:** Events that cannot happen at the same time **Correct Answers:** D **CorrectAnswerText:** Mutually exclusive events are events that are unable to happen simultaneously. ### Question 5 **Question Type:** multiple\_choice **Question Text:** What is the formula of the conditional probability? **Answer A:** P(AB) = P(A and B) / P(B) **Answer B:** P(AB) = P(B) / P(A) **Answer C:** P(A/B) = "The probability of A given B is P(AB) = P(B) / P(A) **Answer D:** P(A et B) = P(A) + P(B) **Correct Answers:** A **CorrectAnswerText:** P(A|B) = P(A and B) / P(B) "The conditional probability is given by the formula P(A|B) = P(A and B) / P(B), provided that P(B) > 0." ### Question 6 **Question Type:** multiple\_choice **Question Text:** What probability distribution is often used for events that occur randomly over time or space? **Answer A:** Exponential Distribution **Answer B:** Normal Distribution **Answer C:** Poisson Distribution **Answer D:** Binomial Distribution **Correct Answers:** C **CorrectAnswerText:** The Poisson Distribution is used for events that occur randomly over time or space. ### Question 7 **Question Type:** multiple\_choice **Question Text:** What characteristic is not a part of probability distributions? **Answer A:** Variance **Answer B:** Sign **Answer C:** Standard deviation **Answer D:** Mean **Correct Answers:** B **CorrectAnswerText:** The characteristics of probability distributions include the mean, variance, and standard deviation. The "sign" is not part of it. ### Question 8 **Question Type:** multiple\_choice **Question Text:** What is the relationship between independent events A and B? **Answer A:** P(A|B) > P(A) **Answer B:** P(A and B) = P(A) + P(B) **Answer C:** P(A|B) = P(A) **Answer D:** P(A|B) = P(B) **Correct Answers:** C **CorrectAnswerText:** For independent events, P(A|B) = P(A) "This means that the occurrence of event B does not affect the probability of A."
