Probability that event A does not occur: P(A’): **0.7**

Probability that event B does not occur: P(B’): **0.5**

Probability that event A and/or event B occurs P(A∪B): **0.65**

Probability that event A and event B both occur P(A∩B): **0.15**

Probability that either event A or event B occurs, but not both: **0.5**

Can you add a third probability event for event C? You can make it to where it is not required to fill unless necessary. That would be amazing! Written as:

Probability of event C: P(C)

Zach,

Nicely done, but you are assuming A and B are independent. You should state this assumption somewhere. Even better, allow the user to specify the conditional probability of B given A or A given B.
