Bayes Theorem|教育線上App不用買

Do you have cancer? Should you dial 911? Does he/she like you?

Get answers to tough questions with Bayes Theorem, an app built around the most important law of probability theory. First introduced in the 18th century, Bayes Theorem is used today in everything from spam detection to cancer diagnosis. This app allows you to unlock the potential of this centuries-old theorem and answer everyday questions, including:

· Is he/she taking drugs?

· Does he like me?

· Am I going to pass this math test?

· Does she like the Beach Boys?

Bayes Theorem is highly versatile. Besides the questions mentioned above, you can also develop your own question and have it answered within the app.

Get your questions answered. With math.

How does Bayes Theorem work?

Here's an example: Bob is randomly chosen and tested for a disease that affects 1% of the population. Bob tests positive - and the test is accurate 95% of the time. What is the probability that Bob has the disease?

Surprisingly enough, the answer is not 95%.

The probability, as calculated using Bayes Theorem, is actually 16%. This is because it's so unlikely for Bob to have the disease - it only affects 1% of the population. It's more likely for Bob to not have the disease and test positive than it is for Bob to have the disease and test positive.
