It's possible in the same way its possible that you will spontaneously phase through the floor due to a particular outcome of atomic resonance. Possible, but so unlikely it almost certainly has not, nor ever will happen.

Might something a small as a grain of sand have phased through a solid barrier as thin as a piece of paper somewhere on earth, at some point over billions of years? Sure. Paper is still pretty thick, and a grain of sand is enormous on the atomic scale, but it's at least in the realm of practical probability. When you start talking about cum(P) events in the realm of 1/1e30 you simply can't produce a scenario with that many dice rolls. If our population was 8 quadrillion and spanned a 40,000 year empire we would likely still never see an individual 11σ from the mean.

The probability is exactly zero by definition. The maximum score on a test is a raw score of 100%. Tests are normalized to have the reported scores fit a normal distribution. An out-of-distribution score indicates an error in normalizing the test.

In other words, the highest IQ of every living person has a defined upper bound that is dependent on the number of living people and it is definitionally impossible to exceed this value. Reports of higher values are mistakes or informal exaggerations, similar to a school saying a student is one that you would only encounter in a million years. By definition it is not possible to have evidence to support such a statement.
