The two events have the same probability of happening.
When you are asked what is the probability of drawing "thing a" when you have only the same amount of "thing b," is called an equally likely event. For example: In a hat you have 8 black marbles and 8 black marbles. Since there the same amount of both, the chance of picking a black marble is 50% and picking a blue marble is 50%. This is an equally likely event.
All that it means is that you have chosen to divide up the event space into events that are equally likely.

equally likely means as likely as the other side ex: 1 piece of candy on this side,1 piece of candy on that side

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.
it means that it has a 50% chance of happening
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.
to "serve" out something equally.
The two events have the same probability of happening.
It means the probability is equal for all of them. If you were to grab one the chances of grabbing another are the same. But in this case it is only equally likely for the red and the green. But if you were to grab two the chances would be equally likely because of the amount of spinners.
Two events are equally unlikely if the probability that they do not happen is the same for each event. And, since the probability of an event happening and not happening must add to 1, equally unlikely events are also equally likely,
