Compound probability can be defined as the probability of the two events which are independent. It can be defined as the multiplication of the probability of two events that are not dependent.

Probability theory is a branch of mathematics that deals with the subject of probability. Although there are many different concepts of probability, probability theory expresses the definition mathematically through a series of axioms. Usually, these axi…

Conditional Probability

By definition, the term probability is expressed as a part of mathematics where the chance of an event that may either occur or not is evaluated and expressed in numerical terms. The range of the value within which probability can be expressed is between…

Textbook Question

Chapter 8.3, Problem 68E

Lottery An article in The New York Times discussing the odds of winning the lottery stated,

“And who cares if a game-theory professor once calculated the odds of winning as equal to a poker player's chance of drawing four royal flushes in a row, all in spades—then getting up from the card table and meeting four strangers, all with the same birthday?”

Calculate this probability. Does this probability seem comparable to the odds of winning the lottery? (Ignore February 29 as a birthday, and assume that all four strangers have the same birthday as each other, not necessarily the same as the poker player.)

Determine if each statement is true or false. If the statement is false, provide a brief explanation: a) There exists x = R such that √x2 = -x. b) Let A = {x = ZIx = 1 (mod 3)} and B = {x = ZIx is odd}. Then A and B are disjoint. c) Let A and B be subsets of a universal set U. If x = A and x/ € A - B,then x = An B.| E d) Let f : RR be defined by f (x) = 1 x + 2 1. Then f is surjective.
