WebbNow find the probability that the number rolled is both even and greater than two. Solution: In both cases the sample space is S = {1,2,3,4,5,6} and the event in question is the intersection E ∩ T = {4,6} of the previous example. Since the die is fair, all outcomes are equally likely, so by counting we have P(E ∩ T) = 2. WebbIn probability theory, a probability density function ( PDF ), or density of a continuous random variable, is a function whose value at any given sample (or point) in the sample space (the set of possible values taken by the random variable) can be interpreted as providing a relative likelihood that the value of the random variable would be ... progressive economists network
