Answer:
37.27% probability that he or she will have a heart attack.
Step-by-step explanation:
Bayes Theorem:
Two events, A and B.
In which P(B|A) is the probability of B happening when A has happened and P(A|B) is the probability of A happening when B has happened.
In this question:
Event A: Periodontal disease
Event B: Heart attack
Researchers discovered that 82% of people who have suffered a heart attack had periodontal disease, an inflammation of the gums.
This means that 
Only 33% of healthy people have this disease.
This means that 
Suppose that in a certain community heart attacks are quite rare, occurring with only 15% probability.
This means that 
If someone has periodontal disease, what is the probability that he or she will have a heart attack
37.27% probability that he or she will have a heart attack.
Answer:
D
Step-by-step explanation:
if you were to chose c you would find that to negatives make a positive and the first negative has to be there so d would be the best possible answer

Answer:
Javier,16,12
Step-by-step explanation:
From the first bag, we can pull a 1,2 or 3. That would go on the first line of the tree diagram
From the 2nd bag, we can draw a 4,5, or 6. That goes on the the second line under each number
From the 3rd bag, we can draw a 7,8, or 9. That goes on the the third line under each number
Javier drew the correct tree diagram.
1,3,5,7,9 are odd numbers. We must have at least 2 of these numbers
1,4,7 2,5,7 3,4,7
1,4,9 2,5,9 3,4,9
1,5,7 3,5,7
1,5,8 3,5,8
1,5,9 3,5,9
1,6,7 3,6,7
1,6,9 3,6,9
There are 16 total where there are at least two odd numbers
Multiples of 4 are 4 and 8
We must have either a 4 or an 8 but not both
1,4,7 2,4,7 3,4,7
1,4,9 2,4,9 3,4,9
1,5,8 2,5,8 3,5,8
1,6,8 2,6,8 3,6,8
There are 12 outcomes
