Assessment 9-1B: Exercise 3 In an open refrigerator, there are seven different types of diet soda, four different types of regular soda, and two types of bottles of water. a. Suppose Evan chose a bottle from the refrigerator at random. Could we realistically say that the probability of choosing a diet soda is 7/3? Why or why not? b. If there are 16 total bottles of diet soda, 8 total bottles of regular soda, and 4 total bottles of water, what is the probability of each of the following:
(i) Choosing a bottle of diet soda when a bottle is chosen at random
(ii) Choosing a bottle of regular soda when a bottle is chosen at random
(iii) Choosing a bottle of water when a bottle is chosen at random*…show more content…*

## The Touchstone Of Life By Loewenstein

1053 Words | 5 PagesIn “The Touchstone of Life”, Loewenstein talked about the concept of entropy from the viewpoint of “information theory.” In the thermodynamic viewpoint, the concept of entropy is the “transformation of heat to work.” However, in general chemistry the viewpoint of entropy is the “measure of disorder.” There are some different and similar between 3 viewpoints. The common in 3 viewpoints are that they were trying to explain the second the law of thermodynamics. Also, Boltzaman stated that entropy is

## Probability Of A Sequence Of Rational Numbers

1931 Words | 8 PagesAbstract Bernoulli numbers evaluate the probability of a sequence of rational numbers. They’re found commonly within many types of mathematics: Number Theory, Euler-Maclaurin summation, and power series are some exampled. Once Bernoulli’s ideas were published, it gave flight to many mathematicians in the field of probability. You can consider Jakob Bernoulli as the founding father of probability.
