Objective:
- To become well-learned in the way of the while loop
Resources:
Directions:
- Prompt the user for a number N (this will be our total number of test points
- Create a variable for our numHits
- Write a loop that runs N times
- Generate random numbers for x and y between 0 and 1.0 by using random.random()
- Use the distance formula to calculate the distance from (0, 0) to (x, y)
- Increment (Increase by 1) numHits if the distance is less than 1
- Calculate an estimate of pi
- successProbability = numHits / N
- pi = successProbability / 4
- Print out your estimate of pi
