What does equally likely as unlikely mean in probability?
If you are using it in terms of an event (aka rolling a dice, flipping a coin, etc.) it means there is a 50% chance of it happening and not happening. It can be equal to 50% or 1/2 or anything equal to those!
What is the definition of theoretical probability?
Theoretical probability is the probability of an event when all outcomes are equally likely. With theoretical probability, you determine the probability by dividing the number of ways the event can occur by the total number of equally likely outcomes.
What does unlikely mean in probability?
In common usage, unlikely means a low probability of occurrence. But as a term in mathematics, an unlikely event is not rigorously defined as a "low number" is subjective. Certainly, in a comparative sense, i.e. event A is less likely to occur than event B, we can state that the probability of occurrence of A is less than B.
What probability is based on knowing all of the equally likely outcomes of an experiment?
Theoretical probability
What are equally likely event?
Two events that have the same chance of happening. For example, if I flip a coin the event of obtaining a 'head' is equally as likely as the event of obtaining a 'tail'. But equally likely does not mean 0.5 probability. It's possible that it's equally likely that someone in Ontario, Canada will die from being stung by a wasp as from being electrocuted in their kitchen at home. Neither event is very likely but the two events could be equally likely.
