What is the distance formula in a coordinate plane?

Front

How do you calculate the length of a segment using other segment lengths?

Back

If GH = FH - FG, you can find the length of segment GH by subtracting the length of segment FG from FH.

Front

What is the probability of an event?

Back

Probability is the measure of the likelihood that an event will occur, calculated as the number of favorable outcomes divided by the total number of possible outcomes.

What is the point-slope form of a linear equation?

Front

How do you find the probability of selecting two marbles without replacement?

Back

To find the probability of selecting two specific marbles without replacement, multiply the probability of selecting the first marble by the probability of selecting the second marble after the first has been removed.

Front

What is the formula for the probability of spinning a specific color on a spinner?

Back

The probability of spinning a specific color is calculated as: P(color) = (Number of sections of that color) / (Total number of sections on the spinner).

Front

Define 'favorable outcomes' in probability.

Back

Favorable outcomes are the outcomes in a probability experiment that correspond to the event of interest.

Front

What is the total number of outcomes in a probability experiment?

Back

The total number of outcomes is the complete set of all possible results of a probability experiment.

Front

Explain the concept of 'without replacement' in probability.

Back

'Without replacement' means that once an item is selected, it is not put back into the pool of items for subsequent selections.

Front

What is the formula for calculating the probability of independent events?

Back

For independent events A and B, the probability of both events occurring is: P(A and B) = P(A) * P(B).
