Magnetic resonance imaging (MRI) is a process that produces internal body images using a strong magnetic field. Some patients become claustrophobic and require sedation because they are required to lie within a small, enclosed space during the MRI test. Suppose, that 20% of all patients undergoing MRI testing require sedation due to claustrophobia. If five patients are selected at random, find the probability that the no. of patients in these five who require sedation is (a) Find the probability that at least three of these five patients who require sedation? (b) find the probability that none of them require sedation?

Some patients become claustrophobic and require sedation be- cause they are required to lie within a small, enclosed space during the MRI test. Suppose that 20% of all patients undergoing MRI testing require sedation due to claustrophobia. If 5 patients are selected at random, find the probability that a least 2 patients will need sedation. Find the mean and Standard deviation
