Suppose you are working in a hospital with the patients who come after a heart attack. You found from the hospital records of the past that, out of 120 patients coming after a heart attack 6 patients died. a) [1 mark] What is the probability that a patient with a heart attack dies of the attack? b) [3 marks] Suppose we have 7 patients who had a heart attack. What is the probability that the majority of them will survive? Question No-04 [4 marks] Suppose you are at the reception of a university club at the annual club festival. The time between the successive arrivals of two guests at the stall is exponentially distributed with the mean of 5 minutes. What is the probability of you passing YZ minutes without welcoming any new guest? Suppose you are working in a hospital with the patients who come after a heart attack.
