Explain the mathematical laws of probability

charle [14.2K]

In probability theory, the law (or formula) of total probability is a fundamental rule relating marginal probabilities to conditional probabilities. It expresses the total probability of an outcome which can be realized via several distinct events. I hope this answers your question! :)

A population is normally distributed with mean 18 and standard deviation 1.7. (a) Find the intervals representing one, two, and

elena55 [62]

Answer:

Interval within 1 standard deviation: (16.3,19.7)

Interval within 2 standard deviation: (14.6, 21.4)

Interval within 3 standard deviation: (12.9, 23.1)

Step-by-step explanation:

We are given the following in the question:

Population mean, $\mu$ = 18

Standard deviation, $\sigma$ = 1.7

We have to find the following intervals:

Interval within 1 standard deviation:

$\mu \pm 1\sigma\\=18 \pm 1.7\\=(16.3, 19.7)$

Interval within 2 standard deviation:

$\mu \pm 2\sigma\\=18 \pm 2(1.7)\\= 18 \pm 3.4\\=(14.6,21.4)$

Interval within 3 standard deviation:

$\mu \pm 3\sigma\\=18 \pm 2(1.7)\\= 18 \pm 5.1\\=(12.9,23.1)$

Mariana is taking a multiple choice test with a total of 80 points available. Each question is worth exactly 4 points. What woul

Sladkaya [172]

Mariana's score if got right if she got 5 wrong is 60 points.

Mariana's score if got right if she got xx wrong is 80 - 4xx.

<h3>What is Mariana's score?</h3>

The first step is to determine the number of questions that Mariana got right. In order to get the number of questions that she got right, subtract the total number of number of questions from the questions that he got wrong.

Questions that Mariana got right = total number of questions - questions he got wrong

Total number of questions = total number of points / point of each question

Total number of questions = 80 / 4

Total number of questions = 20

Questions that Mariana got right if he got 5 wrong = 20 - 5 = 15

Mariana's score = questions she got right x number of points per question

Mariana's score = 15 x 4 = 60 points

Questions that Mariana got right if he got x wrong = 20 - xx

Mariana's score = (20 - xx) x 4

Mariana's score = 80 - 4xx
