Multiplying the probabilities together gives us the probability of all three events occurring in sequence:

0.075 x 0.052 x 0.006 = 0.00002394

To convert this probability to odds, we can use the formula:

odds = probability / (1 - probability)

Plugging in the probability above, we get:

odds = 0.00002394 / (1 - 0.00002394) = 1 in 41,778.2

This suggests that the odds of a basketball team losing as a 4 seed to a 13 seed in 2021, as a 3 seed to a 15 seed in 2022, and as a 1 seed to a 16 seed in 2023 are approximately 1 in 41,778.2.
