Description

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, its 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: - Odds - Survey Results - Venn Diagrams - Bayes Theorem - Permutations - Combinations - Taking Balls from Urns - Replacement vs. Non-Replacement - Independent Events - Dice - Roulette - Lottery - Poker - General Card Problems - Expected Value - Birthday Problem - Normal Distributions - Poisson Distributions Please note: there are multiple solvers, but there arent solvers for every topic.

The permutation calculation is simply a factorial! Are you kidding? That is not the "formula" for calculating permutation! I want my money back!

Great App!

This app makes it very easy to understand probability. The updated version with permutations and combinations is extremely helpful, especially with the tutorial sections and the solver sections.

Amazing Probability Application

HoustonJudge · 15 years ago

I tried this little app and I really dont know how these probabilities work but I guess the answers could be considered true. Im not sure if I will be using this program a lot but if these probabilities are correct, then this will make this a pretty interesting app.

Excellent Probability App

GadgetGal50 · 15 years ago

Probability Pro is extremely helpful for solving most probability problems. The solvers are excellent, and combined with the formulas and examples, understanding probability has been made very clear. This app has been invaluable in working through and checking my math homework. Overall, it’s been an excellent investment and a valuable time-saver.

Thank you for this app!

I was struggling in class, I got this app, and probability is making sense now! Great app!

Not what it says
