What is Basic Probability?

Back

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

What is Conditional Probability?

Back

Conditional Probability is the probability of an event occurring given that another event has already occurred, denoted as P(A|B).

Front

How do you calculate the probability of an event?

Back

The probability of an event is calculated as the number of favorable outcomes divided by the total number of possible outcomes.

Front

What is the formula for Conditional Probability?

Back

P(A|B) = P(A and B) / P(B), where P(A and B) is the probability of both events occurring.

What is the probability of spinning an even number on a spinner with numbers 1 to 6?

Back

In a two-way table, how do you find the probability of a specific outcome?

Back

Divide the number of occurrences of the specific outcome by the total number of observations.

Front

What does a Venn diagram represent in probability?

Back

A Venn diagram visually represents the relationships between different sets, showing how they overlap and the probabilities of different outcomes.

How do you find the probability of drawing a specific color marble from a bag?

Back

Divide the number of marbles of that color by the total number of marbles in the bag.

What is the probability of an event that cannot happen?
