WebJun 3, 2024 · Probability: Unordered, with replacement. The number of possible outcomes is not 10 4 / 4!, that's not even an integer. In order to count outcomes, we need to first define what we mean by outcome, that is, we have to describe the sample space. Also, even though ultimately order does not matter, the number of outcomes is not ( 10 4). WebSampling is called without replacement when a unit is selected at random from the population and it is not returned to the main lot.
