Assume that the random variable X is normally distributed, with mean u - 51 and standard deviation o = 8. Compute the probability. Be sure to draw a normal curve with the area corresponding to the probability shaded. P(X s 42) Which of the following shaded regions corresponds to P(X s 42)? O A. X B. c. O O X X P(X $ 42) = 2643 (Round to four decimal places as needed.)
