2022年1月11日 · Determine if two events are mutually exclusive and/or independent. Apply the "Or" rule to calculate the probability that either of two events occurs. Apply the "And" rule to calculate the probability that both of two events occurs. Many probabilities in real life involve more than one event.

2021年1月5日 · Given two events, A and B, to “find the probability of A or B” means to find the probability that either event A or event B occurs. We typically write this probability in one of two ways: P(A or B) – Written form; P(A∪B) – Notation form; The way we calculate this probability depends on whether or not events A and B are mutually ...

2023年10月29日 · When we combine two outcomes to make a single event we connect the outcomes with the word “and” or the word “or.” It is very important in probability to pay attention to the words “and” and “or” if they appear in a problem.

This section will take a look at probability involving the concepts of "AND" and "OR". It will be observed that there is a working relationship between set theory and probability.

2023年1月14日 · It is very important in probability to pay attention to the words “and” and “or” if they appear in a problem. The word “and” restricts the field of possible outcomes to only those outcomes that simultaneously describe all events. The word “or” broadens the field of possible outcomes to those that describe one or more events.

What is the Probability of A and B? The probability of A and B means that we want to know the probability of two events happening at the same time. There’s a couple of different formulas, depending on if you have dependent events or independent events. Formula for the probability of A and B (independent events): p (A and B) = p (A) * p (B).

Learn the and/or rules of probability and how to use tree diagrams effectively with BBC Bitesize GCSE Maths.

In probability, there's a very important distinction between the words and and or. And means that the outcome has to satisfy both conditions at the same time. Or means that the outcome has to satisfy one condition, or the other condition, or both at the same time.

Determine the probability of events that can happen separately from one another. With simple equations, understand how likely combinations of events are. Try our app!

Use the OR probability formula to find the probability of obtaining at least one head in two coin tosses. You can directly apply the formula for the OR probability:
