Answer:
0.069 = 6.9% probability that he or she will have a heart attack
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It 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 question:
Event A: Does not have periodontal disease
Event B: Has a heart attack.
Probability of not having a periodontal disease:
100 - 80 = 20% of 10%(had a heart attack).
30% of 100-10 = 90%(did not have a heart attack). So
Intersection of A and B:
Not having the disease, suffering a heart attack, so 20% of 10%.
What is the probability that he or she will have a heart attack?
0.069 = 6.9% probability that he or she will have a heart attack
It is given in the question that
Han wants to buy a $30 ticket to a game, but the pre order tickets are sold out. He knows there will be more tickets sold the day of the game, with a markup of 200%.
So Han expect to pay
for the ticket if he buys it the day of the game.
That is
