Compute the probability of an event and of compound events. P  А Formally, we de ne probability as a function from the space of sets to the space of real values between 0 and 1 as follows. The probability of the sure event is 1. Statistics: Elementary Probability Theory. Let a space of elementary events Distinguish between discrete and continuous random variables. A 7. Probability of picking 2 green balls and 1 blue ball = 4/14 * 3/13 * 5/12 = 5/182. De nition 1 (Probability) Probability is a real-valued set function P that assigns, to each event A in the sample space S, a number P(A) such that the following three properties are satis ed: 1. Elementary properties of probability Three properties: (2)The sum of the probabilities of mutually exclusive outcomes is equal to 1 P(E1) + P(E2) + … + P(En) = 1 (Property of exhaustiveness –→ all possible events) Collectively exhaustive event: A set of events that includes all the possible events. space of elementary events be given and this А Thus, the higher the probability of a given event, the more likely it is to occur. 3.If A and B are mutually exclusive, then: The sum of the probabilities of an event and its complementary is 1, so the probability of the complementary event is: The probability of an impossible event is zero. The probability of the sure event is 1. p(S) = 1 3.If A and B are mutually exclusive, then: p(A ∪ B) = p(A) + p(B) Probability Properties 1… defined on events of  Example 3: What is the probability that Ram will choose a marble at random and that it is not black if … Copulas 98 9.

P robability Probability is the measure of the likelihood that an event will occur in a Random Experiment. If A is a defined event, then the probability of A occurring is expressed as P (A). Absolutely Continuous Probability Laws 111 Chapter 4. Probability & Key Terms. another green ball = 3/13. is called the probability of an event A. Probability is the chance that something will happen, or how likely it is that an event will occur. Independence 110 4. Let a space of elementary events E be given and this space consists of N equally likely elementary events, among which there are n events, favorable for an event A. Use discrete and continuous distribution models to calculate probabilities for appropriate random variables.

If A is a defined event, then the probability of A occurring is expressed as P(A).

Е A probability gives the likelihood that a defined event will occur. 0 ≤ p(A) ≤ 1 2. 2. For example, if A and B are events, then the probability that event A occur or B occur, but not both is P ((A∪B)\(A∩B)) = P ((A\B)∪(B \A)) = P(A)+P(B)−2P(A∩B). 7. an event  It is quantified as a positive number between 0 (the event is impossible) and 1 (the event is certain). I like to spend my time reading, gardening, running, learning languages and exploring new places. Definition and basic properties probability of an event  The probability of an event is the likelihood that the event will happen. (the probability of some event occurring from S is unity) Axiom 3 If A and B are mutually exclusive events in S, then U = +( ) (the probability function is an additive set function) The classical definition of probability defines the probability function as = ( º) () for any event A in the sample space S 9.
