No, it's a steady 8% chance across the board. The likelihood might be less than 1%, tho.

In probability theory and statistics, the binomial distribution with parameters n and p is the discrete probability distribution of the number of successes in a sequence of n independent yes/no experiments, each of which yields success with probability p.

In this case success is an earring dropping.
The formula is:

Probability or p of a "yes" is 8% or .08.
[You must be logged in to view images. Log in or Register.] = (9 C 5 )(.08)^5 * (1-.08)^(9-5) = 0.0002958% chance of getting a "yes" 5 out of 9 times with a probability of 8%.
It's fully possible that it was just "bad luck," but chances are there is something else at play. For comparison, the odds of getting struck by lightning in your life are .00033%. You literally have a better chance of getting struck by lightning than getting 5 earrings out of 9 kills @ 8% drop rate.
