What does "probability" mean in mathematics?

• The area of mathematics known as probability explores potential outcomes of events, along with the likelihoods and distributions of those occurrences.
• The number of possible outcomes is divided by the total number of possible outcomes to determine probability. Probability and odds are two distinct ideas.
• Odds are calculated by dividing the chance of a given event by the probability that it won't.

From the given condition,

     total number of  different ways  = 4⁵   ⇒ 1024
