CFA Level 1 - 101 Must Knows 368 Questions with Verified Answers Addition Rule of Probability - CORRECT ANSWER ADDITION: P(A or B) = P(A) + P(B) - P(AB) Roy's Safety First Criterion - CORRECT ANSWER Safety First Ratio = (E(R) - Rₜ) / σ Larger ratio is better If (Rₜ) is risk free rate, then it becomes Sharpe Ratio Sharpe Ratio - CORRECT ANSWER Sharpe Ratio = (E(R) - RFR) / σ Larger ratio is better If (Rt) is higher than RFR, then it becomes Safety First Ratio Central...

WGU C207 Data-Driven Decision Making (Latest 2023/ 2024 Update) Vocabularies with Verified Definitions- 100% Correct V: Independent Events Answer: Events that are not effected by other trials or events, V: Complimentary events Answer: Events with two outcomes that are the only possible outcome. Like flipping a coin. V: Conditional Probability Answer: The probability of an event occurring, given that another event has already occurred. P(B|A) = P(A and B)/P(A) ...

Probability - Independent Events The occurrence of one event does not affect the probability of the other. -If A and B are independent events, then P(A and B) = P(A)•P(B) Theoretical (Classical) Probability Count the number of outcomes and divide by the total possible outcomes. Theoretical probability requires that the experiment be fair. Empirical Probability (Relative Frequency) Perform the experiment multiple times (trials), count the number of times the event occurs and divided...

Data points only. Measurement of a scores relationship to the mean. A statistical measure that indicates the number of standard deviations a data point is from its mean. correct answer: Z-Score How far a set of numbers are spread. Used for Data set. Hint Words = Risk, spread. correct answer: Variance A method for finding the probability that both of two events occur. When the probabilities of multiple events are multiplied together to determine the likelihood of all of the events happeni...
