Independent and Dependent Probability

Front

What is independent probability?

Back

Independent probability refers to the likelihood of an event occurring that is not affected by the occurrence of another event.

Front

What is dependent probability?

Back

Dependent probability refers to the likelihood of an event occurring that is affected by the occurrence of another event.

How do you calculate the probability of two independent events occurring?

Back

To find the probability of two independent events A and B occurring, multiply their probabilities: P(A and B) = P(A) * P(B).

Front

How do you calculate the probability of two dependent events occurring?

Back

To find the probability of two dependent events A and B occurring, multiply the probability of the first event by the conditional probability of the second event: P(A and B) = P(A) * P(B|A).

What is the probability of drawing two zeros from a set of numbers without replacement?

Back

The probability of drawing two zeros from a set of numbers without replacement is calculated based on the total number of zeros and the total numbers available.

If it rains 2 out of 9 days, what is the probability it rains two days in a row?

Back

The probability that it rains two days in a row is 4/81.

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

Back

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