improbable "what if" games unless all parties involved are seriously
interested in pursuing some specific objective. For example, I've had
multiple experiences with my teenagers wanting to argue "what ifs" that
weren't congruent with my perception of reality, but where no one really
intended to invest the time and effort to provide sufficient specifications
on the discussion such that it could be meaningful. Without careful
specification, "what ifs" can be used to justify anything.
In the larger context of the real world, the response to the highly
improbable string of Heads would involve a significant effort in search of
experimental error or trickery. In the simple context of the test question,
the answer is simply that history has no effect on subsequent trials and the
expected probability would be 50%.
Meaning is always dependent on context.
