comment Sampling from a Convex Body with Many Extremal Points
Not nearly as fast as you ask for, but you can approximate the convex hull by the hull of a smaller, possibly random subset of the points. $e^{cn}$ should suffice for a good approximation.

comment Bounds or approximations for the conditional probability of an event involving correlated random variables
At this generality: it lies between $0$ and $1$ (inclusive). Perhaps if you are more specific...

Is this a homework problem?

comment An intutive reason why a “distance” metric may be a poor one for a procedure where we attempt to modify a string (mutating 0 OR 1 bits)
It is not clear what exactly you are trying to achieve. Are you trying to minimize the expected time to hit a target? what options other than 1 and 2 do you have?
