Experimental or Theoretical Probability?
You toss a coin 50 times and you end up with 20 heads and 30 tails

P(H) = 20/50 = 0.4

P(T) = 30/50 = 0.6
Experimental
Theoretical
Cannot be determined
Neither

amistre64 · Answer

are the results an true reflection of an experiment?

or are they approximations and never actually happened in the experiment?

anonymous · Answer

so im guessing its experimental @amistre64

amistre64 · Answer

experimental is a good guess :)

amistre64 · Answer

we can assess the 'true' probability if need be by saying:

$$P(H)=.4\pm 1.96(\sqrt{\frac{.4(.6)}{50}})$$
if memory serves, 1.96 is the zscore related to 95% of the data about the mean.

anonymous · Answer

oh that means its theoretical @amistre64

amistre64 · Answer

yeah, if we have to adjust stuff to get it to work in out theory,  then its theoretical

if we just get the results from performing some experiment, then its experimental.

anonymous · Answer

yup so its theo ratical

amistre64 · Answer

we got 20 heads out of 50 tosses

P(H) = 20/50 is directly from the experiment, so it has to be experimental
