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
Hey there. My name is Zach Bobbitt. I have a Masters of Science degree in Applied Statistics and I’ve worked on machine learning algorithms for professional businesses in both healthcare and retail. I’m passionate about statistics, machine learning, and data visualization and I created Statology to be a resource for both students and teachers alike. My goal with this site is to help you learn statistics through using simple terms, plenty of real-world examples, and helpful illustrations.
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.
