Study Notes
Counting Rules
- The multiplication principle of counting states that the number of outcomes for a series of independent events is the product of the number of outcomes for each event.
- For dependent events, where the outcome of one event affects the outcome of another, the multiplication principle does not apply.
- Permutation is a counting technique that considers the order of items, used when the order in which items are selected matters.
- The permutation formula is nPr = n! / (n-r)!, where n is the total number of objects and r is the number of objects selected.
- Permutations with repetitions involve events that can occur more than once. The formula for permutations with repetitions is n! / (n1! * n2! *... * nr!), where n is the total number of objects and n1, n2, ... ,nr are the numbers of each type of object.
- Repetition is a key factor in distinguishing between combinations and permutations: combinations don't care about order, but permutations do.
- Understanding these counting rules is essential for calculating probabilities and analyzing data in various contexts.
Probability
- Probability is the measure of the likelihood that an event will occur.
- The probability of an event is expressed as a fraction, decimal, or percentage.
- Empirical probability is based on observations and experiments, while theoretical probability is calculated using mathematical formulas.
- Probability problems can be solved using various techniques, including combinations, permutations, and other counting methods.
- Knowing the basic concepts of probability is helpful when decision making that involves risk and uncertainty.
