Answer:
The total distance covered in 1 hour is 4000 meters.
Step-by-step explanation:
The distance Ami'yan runs is 15 minutes = 1 kilometer
Using the unit formula,
The distance ran in 1 minute =
Now, 1 hour = 60 minutes
⇒The distance covered in 60 minutes = 60 x (Distance run in 1 minute)
=
So, the distance covered in 1 hour = 4 kilometer
1 kilometer = 1000 meters
⇒ 4 km = 4 x 1000 meters = 4000 m
Hence, the total distance covered in 1 hour = 4000 meters.
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.
