#Example 1
#A tire company producing tires during 5 days in a week. 4 of tires averagely 
#are failed in a weekly based production. What is the probability
#of at least 3 failed tires production in a day in the company,

    # naive:   math.exp(-mean) * mean**actual / factorial(actual)
    
    # iterative, to keep the components from getting too large or small:
    p = math.exp(-mean)
    for i in xrange(actual):
        p *= mean
        p /= i+1
