AI overview
A random variable is a quantity that takes on different numerical values based on the outcome of a random phenomenon, like rolling a die or measuring tomorrow's temperature. Random variables matter because they allow us to use mathematics and statistics to analyze unpredictable events and make informed decisions despite uncertainty.
