Answer:
The extent to which something is probable; the likelihood of something happening or being the case (Oxford Languages)
Basically, the chance that something happens.
Example: if there are 10 yellow balls, 5 green balls, and 30 red balls in a bag, the probability that I will get a green ball if I mix the bag will be 5/45, or 1/9.
Note: this is an extremely simple explanation, it may not fit the level of math you are in if you are taking a stats class.
I don't disclose my personal insta here lol.
Hope this helps!
