Try to figure these out before looking at the answers: 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.

Dimensionless number ranges from zero to one - with 0 meaning an impossible event and 1 refer to event that is certain to occur. Thus, the probability that any child is selected is 1/5,290 = 0.0002. : An ace that is also red from a deck of cards, Events A and B are independent when the probability of one event, A, is not affected by another event, B, Sample spaces and events, simple probability, and joint probability. The PowerPoint PPT presentation: "Basic Probability Concepts" is the property of its rightful owner. Probability of 0.5 means the event is just as likely to occur as not. What is the probability of selecting a boy from among the 6 year olds?

A probability of 0 indicates that there is no chance that a particular event will occur, whereas a probability of 1 indicates that an event is certain to occur.

The following formula can be used to compute probabilities of selecting individuals with specific attributes or characteristics. If we select a child at random (by simple random sampling), then each child has the same probability (equal chance) of being selected, and the probability is 1/N, where N=the population size.
