- Both happen: p(a da b) – The headline answer. In the default example it reads 15%.
- Ko ɗaya ko duka: P(A ko B) – Default Misali: 65%.

- Ba ɗaya ba – Default Misali: 35%.
- Ba A ba – Default Misali: 50%.
- Ba B ba – Default Misali: 70%.
Dabarar lissafi
P(A and B) = P(A) × P(B) for independent events. P(A or B) = P(A) + P(B) − P(A and B). P(A|B) = P(A and B) ÷ P(B).
Misali da aka warware
With the starting entries (P(A): 50, P(B): 30), the calculator shows both happen: p(a and b) of 15%. It also reports either or both: p(a or b) 65%; exactly one 50%; neither 35%; not a 50%.
