Probability
How likely an event will happen. Ranges between 0 and 1
Probability refers to the measure of the likelihood of an event occurring. It is expressed as a fraction or a percentage between 0 and 1, where 0 indicates that the event is impossible, and 1 indicates that it is certain. It is useful in many fields, including statistics, finance, and science, among others.
To calculate the probability of an event occurring, we need to determine the number of ways that the event can occur divided by the total number of possible outcomes. For instance, if we have two dice and want to know the probability of rolling a 7, we can find the number of ways this can happen by counting the pairs of dice that add up to 7, which is 6 (1+6, 2+5, 3+4, 4+3, 5+2, 6+1). The total number of possible outcomes when rolling two dice is 36 (6*6), so the probability of rolling a 7 is 6/36, or 1/6.
There are two types of probability: theoretical probability and experimental probability. Theoretical probability is calculated based on what we know about the possible outcomes of an event. Experimental probability, on the other hand, is based on actual observations or experiments.
Probability can also be used to calculate the expected value of an event. This is the average value of the outcomes of a random event over time. Expected value is calculated by multiplying each possible outcome with its probability of occurring and then summing up all the products.
In summary, probability is a mathematical concept that is used to measure the likelihood of an event occurring. It is important in many fields and can be calculated using different formulas depending on the situation.
