Question

Basic notes of probability????​

Answer 1

Answer:

A probability is a number that reflects the chance or likelihood that a particular event will occur. A probability of 0 indicates that there is no chance that a particular event will occur, whereas a probability of 1 indicates that an event is certain to occur.

Formula for the probability of A and B (independent events): p(A and B) = p(A) * p(B). If the probability of one event doesn't affect the other, you have an independent event. All you do is multiply the probability of one by the probability of another.

Answer 2

Any probability is a number between 0 and 1. A probability is a proportion, and any proportion is a number between 0 and 1, so any probability is also a number between 0 and 1. An event with probability 0 never occurs, and an event with probability 1 occurs on every trial.
