Give an example of a discrete random variable
WebExample of Discrete Random Variables. You toss a coin 10 times. The random variable X is the number of times you get a ‘tail’. X can only take values 0, 1, 2, … , 10. Therefore, X is a discrete random variable. Let’s look at the probability of getting 8 tails. p 8 (probability of getting 8 tails) falls in the range 0 to 1. WebRandom (Statistics): Governed by or involving equal chances for each of the actual or hypothetical members of a population; (also) produced or obtained by a such a process, and therefore unpredictable in detail. Arbitrary: Derived from mere opinion or preference; not based on the nature of things; hence, capricious, uncertain, varying.
