Question 703185
Assuming every number combination is possible for each digit, there are 10^16 = 10,000,000,000,000,000 (that's 1 followed by 15 zeros...this is the number 10 quadrillion, which is equal to 1000 trillion)


So the probability is 1 out of 10^16 or 1 out of 10 quadrillion, which is a very small chance.
