Step 1 Solution: Let X be the number of recovered patients and n be the sample number of patients under an observation. From the given information, probability that a patient recovers from a delicate heart operation is 0.60 and n=20. Step 2 Here, patients are independent and probability of success is constant. Hence, X follows binomial distribution with parameters n=20 and p=0.60. Then, the mean of the recover patients is Меan %3D пр = 20x0.60 =12 Step 3 The standard deviation of the recovered patients is S tan dard deviation= Jnp(1- p) 20(0.60)(1-0.60) =V4.8 = 2.19
