Family of Curves

A family of curves is a group of curves that are each described by a parametrization in which one or more variables are parameters. In general, the parameters have more complexity on the assembly of the curve than an ordinary linear transformation. These…

XZ Plane

In order to understand XZ plane, it's helpful to understand two-dimensional and three-dimensional spaces. To plot a point on a plane, two numbers are needed, and these two numbers in the plane can be represented as an ordered pair (a,b) where a and b are…

Euclidean Geometry

Geometry is the branch of mathematics that deals with flat surfaces like lines, angles, points, two-dimensional figures, etc. In Euclidean geometry, one studies the geometrical shapes that rely on different theorems and axioms. This (pure mathematics) ge…

Lines and Angles

In a two-dimensional plane, a line is simply a figure that joins two points. Usually, lines are used for presenting objects that are straight in shape and have minimal depth or width.

Please solve the following Probability Problem, please show all work and solve what is asked: HW 1.w. (Special game)The atmosphere has heated up and a fight erupted! There are n + 1players and somebody threw the first punch. Once a person is punched,they punch another person in the group at random. What are the oddsthat after m iterations:a) Nobody punches the person who started it?b) Nobody gets punched twice?Now take it up a notch: imagine the first person punched N other peopleat random, and once someone gets punched, they punch another N peoplein the group at random, and so on. Again, what are the odds that afterm iterations:a) Nobody punches the person who started it?b) Nobody gets punched twice?

Q1. A chest of drawers has 3 drawers. Each drawer has 2 boxes. The boxes of one drawer contain a silver coin in each respectively, the boxes of another a gold coin in each box, and the boxes of the third drawer a gold and a silver coin, respectively. A drawer is selected at random and a box from the drawer is selected at random and opened. The coin is found to be silver. What is the probability that the coin in the other box is gold?
