A PRIORI
a priori knowledge refers to a knowledge of the actual
population, rather than that estimated by observation. Suppose for example that
we pick two red beads and three black beads from a bag; what is the probability
that the next bead we pick out will be red? Without a priori knowledge,
we can only estimate this from the statistics we have observed, so in this case
we might estimate the probability of picking out a red bead as 0.4. But if we
knew, a priori, that there were only two red beads in the bag, then we
would know for certain that the probability of picking out another red bead was
in fact zero.
