    check all possible pairs (total 36 pairs) in that only (4,6),(5,5),(5,6),(6,4),(6,5),(6,6) will not satisfiy atmost 9 (6 pairs) so 36-6=30 prob=30/36=5/6

    ans=5/6

    I kept getting it wrong because I kept forgetting to add the 9s. I was adding only the numbers less than 9

    Failled 3 times without knowing i wouldnt have another try ..ever . Maybe it would be better to warn users about it .. OR after 3 errors , reset the challenge with another question and other parameters .. Or even better just forget about the multiple choice.. And let us code .

    The given answer choices don't match the real answer; should be 1/9

    # Dice # 1
dice_1 = [1, 2, 3, 4, 5, 6]

# Dice # 2
dice_2 = dice_1.copy()

less_than_10 = 0
all_outcomes = 0

# Iterate through
for v1 in dice_1:
    for v2 in dice_2:
# add 1 for every pair to all_outcomes
        all_outcomes += 1
        if v1 + v2 < 10:
# add 1 for pairs that summed up to 9 or below to less_than_10.
            less_than_10 += 1

prob_less_than_10 = less_than_10 / all_outcomes
print(prob_less_than_10)
