Suppose that the probability of having a particular disease is 0.08. Suppose that the probability of testing positive for the di

sease is 0.94 given that a person has the disease and 0.08 given that the person does not have the disease. Given that a person tests positive for the disease, what is the probability that they actually have the disease? (Answer to four decimal places).

Answer:

0.5054

Step-by-step explanation:

This is a question on conditional probability.

We solve using Baye's Theorem of conditional probability

From the question

The probability of having a particular disease = 0.08.

The probability of not having a particular disease = 1 - 0.08 = 0.92

The probability of testing positive for the disease is given that a person has the disease = 0.94

The probability of testing positive given that the person does not have the disease = 0.08

Given that a person tests positive for the disease, the probability that they actually have the disease is

= (0.08 × 0.94)/(0.08 × 0.94) + (0.08 × 0.92)

= 0.0752/0.0752 + 0.0736

=0.0752/ 0.1488

= 0.5053763441

≈ Approximately to 4 decimal places = 0.5054

Answer:

The answer to your question is 68 ft²

Step-by-step explanation:

Data

                           Large square                Small square

base                       10 - 2 = 8 ft                       2 ft

height                         8 ft                                2 ft

Process

1.- Find the area of the large square

Area = base x height

        = 8 x 8

        = 64 ft²

2.- Find the are of the small square

Area = base x height

Area = 2 x 2

        = 4 ft²

3.- Find the total area

Total area = 64 + 4

                 = 68 ft²

jolli1 [7]

The number in scientific notation is 4.901 * 10^7

<h3>How to express the number in scientific notation?</h3>

The number is given as:

Number = 49,010,000

A number in scientific notation is represented as:

a * 10^b

Where a is any number between 1 and 10.

So, we have:

Number = 4.901 * 10^7

Hence, the number in scientific notation is 4.901 * 10^7
