Detailed Answer Key for Test 6a – Multiple Choice Questions

Detailed Answer Key for Test 6a - Multiple Choice Questions

Below is a detailed answer key for Test 6a, which consists of multiple choice questions. Each question is followed by the correct answer and an explanation of why the answer is correct.

  • Question 1: What is the definition of probability?
    • Answer: The likelihood of an event occurring.
    • Explanation: Probability is a measure of how likely it is for an event to occur. It is usually expressed as a number between 0 and 1, where 0 represents impossibility and 1 represents certainty.
  • Question 2: What is the difference between independent and dependent events?
    • Answer: Independent events are not influenced by each other, whereas dependent events are influenced by each other.
    • Explanation: In statistics, independent events are events that are not affected or influenced by each other. The outcome of one event does not affect the outcome of another event. On the other hand, dependent events are events that are influenced by each other. The outcome of one event does affect the outcome of another event.
  • Question 3: What is the formula for calculating the probability of two independent events both occurring?
    • Answer: The probability of two independent events both occurring is calculated by multiplying the probabilities of each event.
    • Explanation: When two events are independent, their probabilities can be multiplied to find the probability of both events occurring. This can be represented by the formula P(A and B) = P(A) * P(B), where P(A) is the probability of event A and P(B) is the probability of event B.
  • Question 4: What is the formula for calculating the probability of either of two mutually exclusive events occurring?
    • Answer: The probability of either of two mutually exclusive events occurring is calculated by adding the probabilities of each event.
    • Explanation: When two events are mutually exclusive, it means that they cannot both occur at the same time. In such cases, the probability of either event occurring can be found by adding the probabilities of each event. This can be represented by the formula P(A or B) = P(A) + P(B), where P(A) is the probability of event A and P(B) is the probability of event B.

Overall, understanding the concepts of probability and being able to calculate probabilities of various events is essential in statistics. This answer key provides detailed explanations for common multiple choice questions on the topic, helping students grasp the concepts effectively.
