Linear Combinations of Random Variables is a part of the VCE Specialist Maths topic Probability and Statistics. A random variable is the outcome of a randomised experiment in which the value is due to chance. Linear combinations are expressions constructed from a set of numbers which are multiplied by a constant. The results of the multiplications are then summed.
In this post, we look at using linear combinations and random variables in the context of probability.
Watch the next video to learn how to use linear combinations to find the multiples, mean and variance of random variables.
This next video uses linear combinations with multiple random variables.
