Simple definition of probability distribution

Webb26 juli 2024 · So: A discrete probability distribution describes the probability that each possible value of a discrete random variable will occur—for example, the probability of getting a six when rolling a die. When dealing with discrete variables, the probability of each value falls between 0 and 1, and the sum of all the probabilities is equal to 1. WebbSo given that definition of a random variable, what we're going to try and do in this video is think about the probability distributions. So what is the probability of the different possible outcomes or the different possible values for this random variable. We'll plot them to see how that distribution is spread out amongst those possible outcomes.

WebbThe chance that something will happen. How likely it is that some event will occur. Sometimes we can measure a probability with a number like "10% chance", or we can use words such as impossible, unlikely, possible, even chance, likely and certain.

Webbprobabilities equal the product of their individual probabilities. This may seem a mouthful, so a simple numerical example will help. If the chance that ‘x’ has a value of 3 is 0.2 and ‘y’ has a value of 2 is 0.3, then the chance ‘x’ is 3 and ‘y’ is 2 is 0.2×0.3=0.06.

Probability is a branch in mathematics that specifies how likely an event can occur. The value of probability is between 0 and 1.
