The probability that a patient with a heart attack dies of the attack is 4%. Suppose we have 4 patients who suffer a heart attack

a) what is the probability that 2 will survive?

b) what is the probability that all will die?

c) what is the probability that less than 3 will survive?

d) what is the probability that all will survive?

Expert Solution

Given:

The probability that patient will die

p(die)= 0.04

The probability that patient will survive is

p(survive) = 1-0.04 = 0.96

Number of patient, n = 4

Here X has binomial distribution

X ~ Binomial (n,p)

Therefore

a) The probability that 2 will survive is 0.0088

b) The probability that all will die is 0.0000

c) The probability that less than 3 will survive is 0.0091

d) The probability that all will survive is 0.8493

4. The probability that a patient recover from a delicate heart operation is 0.9. What is the probability that exactly 5 of the next 7 patients having this operation survive? Of the next 100 patients having this operation, what is the probability that (a) between 84 and 95 indusive survive? (b)fewer than to survive? 5. A co is tossed 400 times. Use the normal curve approximation to find the probability of obtaining (a) between 105 210 heads inclus (b) exactly...

A) Suppose the probability that a mosquito dies when subjected to a 1 unit of insecticide is 0.7, and the probability that a fly dies when subjected to the same dose of insecticide is 0.5. Assuming independence, what is the probability that both the fly and mosquito die when subjected to 1 unit of insecticide B) Suppose A and B are events where the probability that B occurs is 0.3, and the probability that both A and B occur is...

Questions 23–33: Heart Attack Survival, revisited Some people who are having a heart attack do not experience chest pain, although most do. A study of people admitted to emergency rooms with heart attacks compared the death rates of people who had chest pains with those of people who did not have chest pains (Brieger et al. 2004). Of the 1,763 people who had heart attacks without chest pain, 229 died, while of the 19,118 people who had heart attacks with...

(Binomial) The probability that a patient recovers from a delicate heart operation is 0.85. Of the next 7 patients, what is the probability that (a) exactly 5 survive? (b) between 3 and 6 survive (inclusive)? (c) What is the probability that 4 or more patients will NOT recover from the heart operation?

In a large population, 3% have had a heart attack. Suppose a medical researcher randomly selects two people. Let X represent the event the first person has had a heart attack. Let Y represent the event the second person has had a heart attack. Which of the following is true about the two events? X and Y are disjoint. X and Y are independent. None of the above are true. Both (A) and (B) are true. plese show expakin how...

It is felt that first-time heart attack victims are particularly vulnerable to additional heart attacks during the year following the first attack. To estimate the proportion of first-time heart attack victims who suffer an additional attack within one year, a random sample of 300 first-time heart attack patients of Medical College of Georgia was tracked for one year. a) If 254 of the 300 sampled did not suffer an additional heart attack within one year, construct a 95% confidence interval...

Calculate your risk of having a heart attack by completing the American heart association’s Risk Calculator.The calculator requires some health information that you may not know, in that case you will need to guess. However, consider getting that information if you don’t know. Did the result surprise you? Why or why not? Discuss ways you think your diet can be modified to reduce the risk heart attack and/or discuss ways your diet already reduces the risk of heart attack.
