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.

A graph titled "Pregnancy Length in a Population of New Mothers" has a horizontal x-axis labeled "Pregnancy length (in days)" from about 225 to 309 with tick marks at 235, 281, and 294. A normal curve labeled = 267 = 12 is centered above the x-axis at 267. Two vertical line segments extend from the curve to the x-axis at 281 and 294. The area below the curve and between the two vertical line segments is shaded and labeled 281 < x < 294.

The probability that the member selected at random is from the shaded area of the graph is ___. (Round to four decimal places asneeded.)
