# The probability that two integers randomly chosen are primes between then
# is surprisingly related to pi, this probability value is equal to 6/pi**2.
# This was discovered by Cesaro, in 1883.
# This code uses Monte Carlo method to test 10**7 pairs of random integers between
# 1 and 10**10 to approximate numerically the value of pi.
