A statistic is a number that represents a property of the sample. For example, if we consider one math class to be a sample of the population of all math classes, then the average number of points earned by students in that one math class at the end of the term is an example of a statistic. The statistic is an estimate of a population …a) A die is rolled, find the probability that the number obtained is greater than 4. b) Two coins are tossed, find the probability that one head only is obtained. c) Two dice are rolled, find the probability that the sum is equal to 5. d) A card is drawn at random from a deck of cards.

Arithmetic involves the study of numbers, especially the properties of traditional operations, such as: Addition. Subtraction. Multiplication. Division. The arithmetic operators based on these operations are ‘+’, ‘-’, ‘×’ and ‘÷’. Let us learn here all the important topics of arithmetic with examples.Elementary probability Manyoftheprincipalapplicationsofcalculusaretoquestionsofprobabilityandstatistics. …Probability is simply how likely something is to happen. Whenever we’re unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are. The analysis of events governed by probability is called statistics.

even rank order those categories. For example, all we can say is that 2 individuals are different in terms of variable A (e.g., they are of different race), but we cannot say which one "has more" of the quality represented by the variable.
