ANSWER:
STEP-BY-STEP EXPLANATION:
The operation is a multiplication, which is expressed as follows:
The conditional probability that the person has the disease given that the test result is positive is of 0.4750 = 47.50%.
<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 B: Has the disease.
The percentages associated with a positive test is:
- 93.9% of 3.8%(has the disease).
- 4.1% of 100 - 3.8 = 96.2%(does not have the disease).
Hence:
The probability of both a positive test and having the disease is given by:
Hence the conditional probability is given by:

Answer:
Option four, 6b + 4r
Step-by-step explanation:
So the two mini-type equations are joined together with a plus. Which means the parenthesis don't do anything in this particular equation. You simply add all of the same variables together. (r's go w/ r's, b's go w/ b's)
(2b + 3r) + (4b + r)
2b + 4b + 3r + r
6b + 4r
