EXPLANATION
Probabilities are expressed with numbers between 0 and 1 - or 0 to 100% if we're using percents.
An event whose probability of occurring is 1 (or 100%) means that that event will always occur for every experiment that includes that event.
If the probability of the event occurring is between 0.5 and 1 it means that it is more likely to occur than it is to not occur. And viceversa, if it's less than 0.5 then it is more likely to occur.
If the event has a very low probability to occur - for example 0.03, 0.05 etc, it means that it is very unlikely to occur. And viceversa, if the pro
