Riemann Sum
Riemann Sums is a special type of approximation of the area under a curve by dividing it into multiple simple shapes like rectangles or trapezoids and is used in integrals when finite sums are involved. Figuring out the area of a curve is complex hence this method makes it simple. Usually, we take the help of different integration methods for this purpose. This is one of the major parts of integral calculus.
Riemann Integral
Bernhard Riemann's integral was the first systematic description of the integral of a function on an interval in the branch of mathematics known as real analysis.
Given data:
The grades and gender of a group of students regarding to test is tabulated.
Total number of students who gave test, N = 76.
Let B be an event that a randomly selected student gets a grade B in the test.
Number of students who got grade B, x = 31.
Let F be an event that a randomly selected student is a female.
Number of female students, f =29.
Let (B and F) be an event that a randomly selected student is a female and got a grade B.
Number of female students who got grade B, y = 11.
