The probability that the point P lies outside the square is;1 - (2/π)
<h3>How to choose a point in a circle?</h3>
If a is the radius of the circle, then;
Area of the inscribed square = 2a²
Now, area of the circle is;
Area of circle = πa²
Thus, probability that the point lies outside the square is;
Area of between circle and square/area of circle
Area between circle and square = πa² - 2a² = a²(π - 2)
Thus;
P(the point lies outside the square) = a²(π - 2)/πa² = (π - 2)/π = 1 - (2/π)

A score of 85 would be 1 standard deviation from the mean, 74. Using the 68-95-99.7 rule, we know that 68% of normally distributed data falls within 1 standard deviation of the mean. This means that 100%-68% = 32% of the data is either higher or lower. 32/2 = 16% of the data will be higher than 1 standard deviation from the mean and 16% of the data will be lower than 1 standard deviation from the mean. This means that 16% of the graduating seniors should have a score above 85%.
