What is the probability of an event?

Back

The probability of an event is a measure of the likelihood that the event will occur, expressed as a number between 0 and 1.

Front

What is the formula for calculating probability?

Back

The formula for calculating probability is: P(Event) = (Number of favorable outcomes) / (Total number of outcomes).

Front

What does P(Blue) represent in probability?

Back

P(Blue) represents the probability of selecting an item that is blue from a set of items.

How do you calculate the probability of landing on a number greater than or equal to 4 when rolling a die?

Back

To calculate this probability, count the favorable outcomes (4, 5, 6) and divide by the total outcomes (1, 2, 3, 4, 5, 6). Thus, P(>=4) = 3/6 = 1/2.

What is a similar triangle?

Back

Similar triangles are triangles that have the same shape but may differ in size. Their corresponding angles are equal, and their corresponding sides are in proportion.

Front

What is the AA similarity postulate?

Back

The AA (Angle-Angle) similarity postulate states that if two angles of one triangle are equal to two angles of another triangle, then the triangles are similar.

Front

What is the SAS similarity theorem?

Back

The SAS (Side-Angle-Side) similarity theorem states that if two sides of one triangle are in proportion to two sides of another triangle and the included angles are equal, then the triangles are similar.

Front

What is the SSS similarity theorem?

Back

The SSS (Side-Side-Side) similarity theorem states that if the corresponding sides of two triangles are in proportion, then the triangles are similar.

Front

What is the probability of rolling an even number on a die?

Back

The probability of rolling an even number (2, 4, 6) is P(Even) = 3/6 = 1/2.

Front

What does P(Even # or Yellow) mean in probability?

Back

P(Even # or Yellow) represents the probability of selecting an item that is either an even number or yellow from a set of items.
