P(AB)\small P(A \cap B)P(AB) AAA AND BBB, P(AB)\small P(A \cup B)P(AB) AAA OR BBB, P(A)+P(B)P(AB)\small P(A) + P(B) - P(A \cap B)P(A)+P(B)P(AB), P(AB)\small P(A \triangle B)P(AB) AAA XOR BBB, P(A)P(B)+P(B)P(A)\small P(A) *P(B') + P(B) * P(A')P(A)P(B)+P(B)P(A), P((AB))\small P((A \cup B)')P((AB)) neither AAA norBBB, P(A)P(B)\small P(A') * P(B')P(A)P(B). It has the odds of all sorts of different possibilities. Most of them are games with a high random factor, like rolling dice or picking one colored ball out of 10 different colors, or many card games. Allowed values of a single probability vary from 0 to 1, so it's also convenient to write probabilities as percentages. This is because the total outcomes are 6 and one side of the dice has 1 as the value.

If you want to find the probability of two events, that are happening at the same time! I have to believe this one is slightly inaccurate. After recognizing the event type you can solve it with the following probability formulas: Dependent Event Formula: p(A and B) = p(A) * p(B). https://www.cancer.org/research/cancer-facts-statistics.html.
