What is the Bayes Theorem and why is it useful?
In: Mathematics
Bayes theorem basically says that the probability of something, without any evidence, should not be ignored.
Like, imagine this.
99% of all cars are red.
Eye witness testimony is 90% accurate.
A witness says the car was blue.
What color do you think the car was? It may seem like the car was blue since witnesses are pretty reliable, but you can’t ignore the first fact. Bayes theorem tells you the correct probability.
