Using conditional probability, it is found that there is a 0.8462 = 84.62% probability that a woman who gets a positive test result is truly pregnant.
<h3>What is Conditional Probability?</h3>
Conditional probability is the probability of one event happening, considering a previous event. The formula is:

In which
- P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
- P(A) is the probability of A happening.
In this problem, the events are:
- Event A: Positive test result.
The probability of a positive test result is composed by:
- 99% of 10%(truly pregnant).
Hence:

The probability of both a positive test result and pregnancy is:

Hence, the conditional probability is:

0.8462 = 84.62% probability that a woman who gets a positive test result is truly pregnant.

Answer:
Step-by-step explanation:
First you would plot the points- (0,2), (1,4), (2,6), (3,8)
Then if the points make a straight line when you connect them then it makes it a linear equation
To know if it is proportional or not you take the y points and put them over their x points, and if all of them end up with the same number than it is proportional
2/0=0, 4/1=4, 6/2=3, 8/3=8/3, therefore it is not proportional
