what is
probability
Probablity is the liklihood of a certain event happening. For example, There is a 1/6 probability of me rolling a 6 on a standard dice when i roll it once.

Probability is a measure of the likelihood that a particular event will occur. It is represented as a number between 0 and 1, where 0 represents the event is impossible and 1 represents the event is certain to happen. For example, if we flip a fair coin, the probability of it landing on heads is 0.5, as there are two equally likely outcomes (heads or tails).
To calculate probability, we use the formula:
Probability (P) = Number of favorable outcomes / Total number of possible outcomes
Here's an example: Let's say we have a bag with 5 red balls and 3 green balls. The probability of randomly selecting a red ball would be:
P(Red) = Number of red balls / Total number of balls = 5 / (5 + 3) = 5/8
In this case, the probability of selecting a red ball is 5/8, or 0.625.
Probability can also be expressed as a percentage, by multiplying the probability by 100. So in this example, the probability of selecting a red ball would be 62.5%.
Keep in mind that probability is a theoretical concept, and it represents the expected frequency of an event occurring over the long run. In practice, the actual outcomes may differ from the calculated probabilities due to random variation.
