What is the range of probability for any event?

Back

The probability of an event must be contained in the interval [0, 1] or [0%, 100%].

Front

What does it mean for two events to be independent?

Back

Two events are independent if the occurrence of one does not affect the probability of the other occurring.

Front

What is the probability of an event that has no possible outcomes?

Back

The probability is 0.

Front

What does ŷᵢ represent in regression analysis?

Back

ŷᵢ represents the predicted value of the dependent variable based on the regression equation.

Dependent events are events where the outcome of one affects the outcome of another, while independent events do not influence each other.

Front

What is the formula for calculating probability?

Back

Probability = (Number of favorable outcomes) / (Total number of possible outcomes).
