In mathematics, probability and statistics are related to each other but are different concepts. For example, Our life is full of probabilities. Statistics are often related to probability because we use much of the data in determining the possible outcomes. Statistical analysis often uses probability distributions. In a statistical experiment, the sum of probabilities for all possible outcomes is equal to one. Here are some basic probability calculators for easy math calculations.
