Introduction: A fixed coordinate system is a system in which points are represented using a set of coordinates or numbers. The order of coordinates is knIntroduction:Probability is one of the sampling techniques for choosing equivalent elements. These are specified as random sampling. Sampling is helped to develop the sampling frame; selects items randomly. Sampling can be done by substitution. The random sampling hypothesis can be realized using the mean limit theory. Definition: Grouping of independent options is known as random sampling. Random sampling has similar independent probabilities. Random sampling is used to obtain an unbiased sample. The sample of n elements can be selected from the N elements of the population. It involves unpredictable components. The random is able to have the number of types. Random sampling is one of the methods of finding the small representative part of the group of elements. Random sampling is able to choose elements among the inhabitants through identical quotas. Types of random sampling: There are five types of random sampling. Type 1: Simple random sampling. Type 2: Systematic random sampling. Type 3: Stratified random sampling. Type 4: Cluster random sampling.Type 5: Multi-stage random sampling.Explanation:Type 1: Simple random sampling:Simple random sampling is one of the types of sampling. The units of the elements chosen depend on the population with identical probabilities of being selected. Simple randoms are preferred by the population size of N elements. The choice m... center of the sheet... two axes, indicated with a sign, the distances from the origin. Quadrants: The two x and y axes divide the plane into four different regions called quadrants. The dials are represented using Roman numerals and start from the top counterclockwise. Each of the four quadrants is represented as First quadrant: (+,+) Second quadrant: (-,+) Third quadrant: (, -,-) Fourth quadrant: (+,-) Example: Example 1: Find out the location of the quadrant in which the points are (2, 1) and (3, 1). The point is found only in the first quadrant. Solution: Both points are positive, so they will only be in the first quadrant. Example 2: Find out the position of the dial where the points are (-2, -1) and (-3, -1). The point is found only in the fourth quadrant. Solution: Both points are negative, so they will only be in the fourth quadrant.
