For continuous RV Xand for 0 p 1, the pth quantile or 100pth percentile of the distribution of Xis the smallest number q p such that F X(q p) = p The median of a distribution is its 50th percentile. Some Simple Counting Rules Multiplication RuleBasic idea If one operation can be done in n 1 ways and a second operation can be done in n 2 ways then the number of di erent ways of doing both is n 1n 2. In this case, there are three possibilities to consider: 1. (n k)!k!. Solution: Let T denote a positive test result. Solution Total number of events = total number of cards = 52 52 Probability of drawing a queen = 4/52 = 1/13 Now, the total number of cards = 51 51 Probability of drawing a king = 4/51 So, the probability of drawing a king and a queen consecutively, without replacement = 1/13 * 4/51 = 4/ 663 The first lesson the educator can use as an introduction to revise Grade 11 probability rules.

To determine probability, you need to add or subtract, multiply or divide the probabilities of the original outcomes and events. Event: Any outcome or collection of outcomes from some chance process is called an event. In this video we look at what the Counting Principle is and see how to apply it in different situations, by Lea Gaslowitz.

Sample with replacement and order doesn't matter: k+n 1 n. Sum Rule: For disjoint sets S and T, jS[Tj=jSj+jTj Inclusion . We assign the appropriate probabilities to the events shown on the branches of the tree. Then P (T and T and T and T) = (0.32)4 = 0.010. fThe Multiplication Rules and Conditional Probability When the outcome or occurrence of the first Example 4.5. Probability Concepts Discrete Probability If the sample space (i.e., the set of all possible outcomes), , for a given experiment and the set of desired outcomes, , are both countable, the probability that occurs is given by: ( ) ( ) ( ) In sum, the counting techniques previously described in this packet can be applied to by the sample Another problem is to decide whether two events are independent or dependent. 4: Probability and Counting. Applying the Concepts 4-5 Counting Rules and Probability One of the biggest problems for students when doing probability problems is to decide whichformula or formulas to use. 2. 1 Suppose a jar contains 3 red and 4 white marbles. Use a scale from 0 (no way) to 1 (sure . Sum Rule, Product Rule, or something else? Basic Counting Rule; Permutations; Combinations Basic Counting Rules Permutations . If 4 are sold at random, find the probability that: a. The complement rule is used to determine the probability of an event occurring by subtracting the probability of the event notoccurring from 1. Events are usually designated by capital letters. 7- 17 The Addition Rules for Probability Many problems involve ndingthe probability of two or more events. The central objects of probability theory are random variables, stochastic processes, and events: mathematical abstractions of non-deterministic events or measured quantities that may either be single occurrences or evolve over time . Counting Rules- Combination A combination is the number of ways to choose r objects from a group of nobjects without regard to . 5-25 Examples Shakil Shrestha Probability and Counting Rules: 1.
