Area of sector = 1/2 * r^2 * x where r = radius and x = angle in radians
86 = 1/2 * r^2 * pi/4
r^2 = 2 * 86 * 4 / pi = 219
r = sqrt 219
= 14.80
You lay out the triangle formula for area which would be A=(1/2)(b)(h)
plug in for variables
375=(1/2)(23.8)(b)
solve for b
SOLUTION
The total number of females =

if 14 have an A in the class, the number of students without A is:

8 male students do not have an A, therefore the number of female students without an A is:

The probability that a student does not have an A given that the student is female can be calculated thus:
