Simple Probability for two events. For example, if I type “Probability of both A and B happening if A has 50% probability and B has a 40% probability”. Probability calculation here would be 20%. Maybe build out several two event probability calculations:

Probability of A NOT occuring: P(A') 0.5

Probability of B NOT occuring: P(B') 0.6

Probability of A and B both occuring: P(A∩B) 0.2

Probability that A or B or both occur: P(A∪B) 0.7

Probability that A or B occurs but NOT both: P(AΔB) 0.5

Probability of neither A nor B occuring: P((A∪B)') 0.3

Probability of A occuring but NOT B: 0.3

Probability of B occuring but NOT A: 0.2
