Has this ever happened before? Is it a fear of yours that you would never admit in real life?


For something like math...are you ever afraid that you'll stall ...or you'll make a mistake with a basic calculation...or forget how to do something ..or forget how to solve a problem ...and embarrass yourself in from of the class?


Or any other subject?

Three coins are thrown. If there are either 1 or 2 heads, half of the time, two coins selected at random are thrown again. This process is repeated until either there are 0 or 3 heads, or when half of the time it's left alone. What is the probability of 0 heads (or 3 heads) being the final state?

If their was such a think as a random number genorator (RNG) that picked any random number from zero upwards. no limit.

The chance of the RNG picking a previosly selected number is 1/infineity... which effectivly = 0

the chance of it picking any number from 0 to 1,000,000,000,000 = 1,000,000,000,000/infinity = 0

any number divided by infinity is effectivly zero.

but because the RNG can pick a number infinitly large, it could pick infinity

and infitity/infinity = 1

therefore, a RNG that genorates any number larger than zero must genorate and infineitly large number EVERY time.

therefore it is not random at all because it can not pick a finite number.

so its a paradox
