Answer:
The probability that the result is positive is P=0.04475=4.475%.
Step-by-step explanation:
We have the events:
D: disease present
ND: disease not present
P: test positive
F: test false
Then, the information we have is:
P(D)=0.005
P(P | D)=0.99
P(P | ND)=0.04
The total amount of positive test are the sum of the positive when the disease is present and the false positives (positive tests when the disease is not present).

The probability that the result is positive is P=0.04475.
Answer:
6
Step-by-step explanation:
No exact amount of cookies so if its a large batch we'll say there is 45 cookies 45 divided by 1/3 is 15
So 15 divided by 2 1/2 = 6
So your answer is 6.
The answer is .5. That is the answer because .5/10 = .05.
