Independence in Probability and Statistics
Independence you say? In probability, independence means that the occurrence of one event does not affect the occurrence of another event. For example, flipping a coin does not influence the roll of a die. These two events are independent. Similarly, in statistics, two variables are independent if the value of one variable does not affect…
