class 11 math chapter 16- probability

To find the probability of an inclusive event we first add the probabilities of the individual events and then subtract the probability of the two events happening at the same time.



What is an example of a probability?
For example, the probability of flipping a coin and it being heads is ½, because there is 1 way of getting a head and the total number of possible outcomes is 2 (a head or tail). ... The probability of something not happening is 1 minus theprobability that it will happen.

What are the 5 rules of probability?
Addition Rule 1: When two events, A and B, are mutually exclusive, the probability that A or B will occur is the sum of the probability of each event. Let's use thisaddition rule to find the probability for Experiment 1. Experiment 1: A single 6-sided die is rolled. What is the probability of rolling a 2 or a 5?
