Step-by-step explanation:
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:
0.3 or 3/10
Step-by-step explanation:
100%=1 so 30%=0.3
27 and 36
12 is too short to be multiplied by 9, 21 can be multiplied by 3 but not 9 again, 3 can’t go into 45. Which leaves 27 and 36. 3 times 9 equals 27. 3 times 12 equals 36, 9 times 4 equals 36.
Answer:
38
Step-by-step explanation:
Line KP is equal to 180 degrees.
The square on angle OLM means that angle is equal to 90 degrees.
Let angle PLO be represented as x.
That would make our equation be 52 + 90 + x = 180.
Start simplifying down to get x by itself.
180 - 90 = 90
52 + x = 90
90 - 52 = 38
x = 38
