Web24 jul. 2016 · Answer; Conditional Probability. Each of the probabilities computed in the previous section (e.g., P(boy), P(7 years of age)) is an unconditional probability, because the denominator for each is the total population size (N=5,290) reflecting the fact that everyone in the entire population is eligible to be selected. WebFor any event E, we refer to P(E) as the probability of E. Here are some examples. Example 8 Tossing a fair coin. In this case, the probability measure is given by P(H) = P(T) = 1 2.
