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, which can be dependent or independent.

Front

How do you calculate the probability of independent events?

Back

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

Front

How do you calculate the probability of dependent events?

Back

For dependent events, the probability of both events occurring is calculated as: P(A and B) = P(A) * P(B|A), where P(B|A) is the probability of B given A has occurred.

Front

What is the formula for calculating the probability of an event?

Back

The probability of an event is calculated using the formula: P(E) = Number of favorable outcomes / Total number of outcomes.

If a jar contains 2 green marbles, 4 blue marbles, 3 yellow marbles, and 2 black marbles, what is the total number of marbles?

Back

The total number of marbles is 2 + 4 + 3 + 2 = 11.

Front

What is the probability of drawing a green marble from the jar?

Back

The probability of drawing a green marble is P(green) = 2/11.

Front

What is the probability of drawing a yellow marble from the jar?

Back

The probability of drawing a yellow marble is P(yellow) = 3/11.

Front

What is the probability of drawing a blue marble from the jar?

Back

The probability of drawing a blue marble is P(blue) = 4/11.
