About Probability Pro
Pop quiz: you flip a fair coin 50 times. What is the probability that it lands on heads at least 25 times?
The number of computations involved in answering that question is staggering. The formulas can cause nightmares.
"Probability Pro" will tell you that the answer is 55.61% instantly.
How about this classic? In a room of 23 people, what is the probability that at least two people share the same birthday? Believe it or not, it's 50.73%. This powerful application will explain why, and it will calculate the probability for any number of people.
How long would it take you to figure out the answers to those questions without "Probability Pro?" How much time do you want to spend checking your homework?
This application features a rich set of tutorials, examples, and solvers for the following topics:
- Formulas

For a non-math person the advert made it seem user friendly. From what i can tell it is a good app if you already know how the formulas and jargon, but i cant even figure out how to tell it what i need it to solve. Disappointing since i had to pay for it too.

This app is absolutely the most thought out and detailed mathematical applications I've seen. It has breakdowns of the formulas in each situation for the answers you seek. It not only gives u the answers it in detail explains the process of how each formula is applied and helps you to understand how they came to the conclusion. There are also a wide variety of different formulas and calculations to answer almost any answer you are looking for. Statistical. Probabilities, odds etc. Wide range of usefulness.

I downloaded many math apps, some free and some not. I'm getting ready to delete most of them. This one,however, is a keeper. The easiest to use and got me through my class (with an A ). Thanks !

Awful. Can't even calculate basic card math.
