Assume a member is selected at random from the population represented by the graph. Find the probability that the member selected at random is from the shaded region of the graph. Assume the variable x is normally distributed.                           Standardized Test Composite Scores 28633Score mu equals 21.3 sigma equals 5.428 less than x less than 33 x             A graph titled "Standardized Test Composite Scores" has a horizontal x-axis labeled "Score" from about 2 to 40 with tick marks at 6, 28, and 33. A normal curve labeled μ = 21.3 σ = 5.4 is centered above the x-axis at 21.3. Two vertical line segments extend from the curve to the x-axis at 28 and 33. The area below the curve and between the two vertical line segments is shaded and labeled 28 < x < 33. The probability that the member selected at random is from the shaded area of the graph is nothing . ​(Round to four decimal places as​ needed.)
