Suppose that after the first encounter, the Black Widow gets more agitated and aggressive so that the probability of encountering it again goes up by 15% with each subsequent encounter. So it's a 15% probability to touch it the first time, but once you have, then it's 30%, and if you touch it a second time, now it's 45% on the third, and so on. Now what is the probability you will get bitten if you stick your hand under the deck 3 times?
