Nadya [2.5K]

Answer:

O.186 or 18.6%

Step-by-step explanation:

Let s = event of schizophrenia

B = brain atrophy

From our question we have:

P(s) = probability of those suffering from schizophrenia = 1.5% = 0.015

P(B|S) = probability of brain atrophy = 30% = 0.30

P(S') = 1 - 0.015 = 0.985

P(B|S') = 2% = 0.02

Probability Hinckley suffered from schizophrenia

= P(S|B) = P(B|S)P(S)/P(B|S)P(S)+P(B|S')P(S')

= (0.30x0.015)/(0.30)*(0.015)+(0.02)(0.985)

= 0.0045/0.0045+0.0197

= 0.0045/0.0242

= 0.185950

This is approximately 0.186 or 18.6%

The table shows the number of touchdowns Luis scored during his football games.
Wittaler [7]

We are given frequency  distribution in the question

to find the probability distribution from frequency distribution  we need to divide frequency by total number of observations.

Here, total number of observations are 6+10+7+5=28

so , we will have probability distribution table as


X 0 1 2 3

P(x) .21 .35 .25 .17

probability distributiuon describes all possible values that a random variable can take within a given range.

frequency distribution is the presentation that presents  number of observation in given interval.

Write in the missing numbers.<br> ordering intergers
Illusion [34]

Based on the definition of integers, ordering them would depend on if they are negative, positive, or have a zero value.

<h3>How are integers ordered?</h3><h3 />

Integers are whole numbers such as 1, 15, and 55. There are no decimals and they do not come in the form of fractions.

Integers can be negative or positive. Positive integers are always higher than negative integers. For instance, 1 is more than -500,000.

If both integers are negative, the larger looking number is considered smaller. For instance, -5 is more than -55. For positive integers, this is the reverse with larger looking numbers being larger.

An example of the correct order of intergers based on this dataset (1, 52, -800, 86, 5, and -4) is:

= -800, -4, 1, 5, 52, 86
