Magnetic resonance imaging (MRI) is a process that pro- duces 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 duringthe MRI test. Suppose that 21% of all patients undergoing MRI testing require sedation due to claustrophobia. If 7 patients are selected at random, find the probability thatNote: Please keep 4 decimal places in your final answer.a. exactly 2 patients require sedation.b. less than 2 patients require sedation.c. exactly 5 patients require sedation.d. at least 5 patients require sedation.
