Simple and Compound Probability

Front

What is probability?

Back

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

Front

What is a simple probability?

Back

Simple probability refers to the probability of a single event occurring.

Front

What is a compound probability?

Back

Compound probability refers to the probability of two or more events occurring together.

Front

How do you calculate the probability of a single event?

Back

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

Front

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

Back

There are 3 even numbers (2, 4, 6) out of 6 possible outcomes, so P(even) = 3/6 = 1/2.

Front

What is a tree diagram?

Back

A tree diagram is a visual representation of all possible outcomes of an event, showing the paths to each outcome.

Front

How do you find the probability of independent events?

Back

For independent events, multiply the probabilities of each event: P(A and B) = P(A) * P(B).

Front

What is the probability of drawing a red card from a standard deck of cards?

Back

There are 26 red cards in a deck of 52 cards, so P(red) = 26/52 = 1/2.

Front

What is the probability of selecting a blue pair of flip-flops from Kaylee's closet?

Back

Kaylee has 1 red, 3 blue, 2 brown, 5 black, 1 purple, and 4 pink flip-flops. Total = 16. P(blue) = 3/16.

Front

What is the probability of rolling a 3 on a die?

Back

There is 1 favorable outcome (rolling a 3) out of 6 possible outcomes, so P(3) = 1/6.
