6. Programming Question: adapted from Programming Problem 5.39 (p.250) Submit: Final version of the Monte Carlo Program (with thread safety implemented using semaphores) Screen shot of sample results The value of pi can be estimated using a technique known as the Monte Carlo Method Consider a quarter circle inscribed within a unit square (Law-1 unit), as shown in the following figure. Hits Not hits 0.9 Hits We know that the area of the square is 1 unit, while the area of the quarter circle is pi/4 unit, as the radius of the quarter circle is 1 unit. Similarly, the ratio between the probability of randomly selecting a point within the square and the probability of randomly selecting a point within the quarter circle will be 1:pi/4. The Monte Carlo Method makes use of this known ratio to estimate the value of pi
