Unformatted text preview: probability 0.5 means occurs half the time in a very large number of trials the proportion in a small number of tosses can be far from the probability probability describes what happens in very many trials the idea of probability is empirical- we can estimate a real-world probability only by actually observing many trials mathematical probability is an idealization based on imagining what would happen in an indefinitely long series of trials...
