Calculate the following probabilities for a patient about to undergo C

Calculate the following probabilities for a patient about to undergo CABG ( coronary-artery bypass graft) surgery. a. The only possible, mutually exclusive outcomes of the surgery are death, relief of symptoms, ( angina, dyspnea), or continuation of symptoms.The probability of death is 0.02 and the relief of symptoms is 0.80. What is the probability that the patient will continue to have symptoms?b. Two known complications of heart surgery are stroke and heart attack, with probability of 0.02 and 0.05, respectively. The patient asks what chances he has of having both the complications. Assume that the complications are conditionally independent, and calculate your answer.c. The patient wants to know the probability that he will have the stroke given that has a heart attack as a complication of surgery. Assume that 1 in 500 patients has both complications, that the probability of heart attack is 0.05 and that the events are independent. Calculate your answer.
