What's the difference between "Classical Probability" & "Relative Probability".?
2015-06-18 9:00 am
What i read is when we have equally likely events e.g. toss of a coin there is equal probability of both events 'heads' and 'tails' of happening. but in case of relative probability its not example was not satisfactory they say 'Next car coming in garage is lemon' so there is a probability that next car won't be lemon what i don't understand is how lemon car isn't equally likely? as there is a probability zero in case of coin too, the probability is zero for heads if tails coming out probability is zero for tails if head coming out?

Never heard of ''Classical" probability, but I assume you mean ''Theoretical'' probability..??
Well, in short, theoretical is what should happen and ''relative'', what actually happens.
An example should illustrate this idea.
A coin is tossed 100 times and the number of heads and tails obtained is recorded as follows:
Heads => 46, Tails => 54
Relative probabilities are P(Head) = 46/100 and P(Tail) = 54/100
Theoretical are as we know are 1/2 and 1/2 respectively.
Hope this waffle helps.

Thanks for your answer Wayne, One thing i need to clear can i say when we are not given the "number of observed " its Classical probability / theoretical probability and when we are give its Relative probability. ? if yes then still if we are given the repetition of experiment but not the "observed" value, what we'll call it then?
