    • The collection of all possible outcomes, namely [math]S[/math] = {H,T}, is called the sample space. Suppose that we are interested in a subset [math]A[/math] of our sample space; for example, in our case, let A={H} represent heads. Repeat this random experiment a number of times, say [math]n[/math], and count the number of times, say [math]f[/math], that the experiment ended in A. Here [math]f[/math] is called the frequency of the event A and the ratio f/n is called the relative frequency of the event [math]A[/math] in the [math]n[/math] trials of the experiment.
