4.3 Assume that x is normally distributed. At a fixed operating setting, the pressure in a line downstream of a reciprocating compressor is known to maintain a mean value of 12.0 bar with a standard deviation of 1.0 bar based on its history. What is the probability that the line pressure will exceed 13.0 bar during any measurement? 4.4 Consider the toss of 4.
