Assume the random variable «math style=¨font-family:`Times New Roman`¨ xmlns=¨http://www.w3.org/1998/Math/MathML¨»«mi»x«/mi»«/math» is normally distributed with a mean «math style=¨font-size:14px;font-family:`Times New Roman`¨ xmlns=¨http://www.w3.org/1998/Math/MathML¨»«mi»§#956;«/mi»«mo»=«/mo»«mn»86«/mn»«mo»§#160;«/mo»«/math» and standard deviation «math style=¨font-size:14px;font-family:`Times New Roman`¨ xmlns=¨http://www.w3.org/1998/Math/MathML¨»«mi»§#963;«/mi»«mo»=«/mo»«mn»5«/mn»«/math». Find the indicated probability to three significant figures.
