example, finding the value of "irrational π" and calculating "fixed points. In this case, it is better to use the probability algorithm to solve the problem.
Iii. Example
In the numerical probability, the most typical question is "computing definite points". Set f (x) = 1-x2 to calculate the definite point: I = 1000001 (1-x2) dx value.
Analysis: Step 1: plot the Coordinate Map of the function f (x) = 1-x2 in:
Step 2: If we randomly place a vertex into the rectangle, the probability
