Assuming each die has faces numbered from 1 to 20, the probability of rolling two ones is 1/400 or 1:399 against.

The odds of rolling a single one on a 20-sided die is 1 in 20 (1/20). Since the rolls are independent events, the odds of rolling two ones on two 20-sided dice would be (1/20) * (1/20), which simplifies to 1 in 400 (1/400).
