I am watching Bayes Theorem Mathamatical formula vidoe from Week 1 of Probability Course.
I saw that he is explaining about the Bayes Formula and in around middle of the video he put in the values in the final formula of Bayes Theorem, and he initially has some values for P(sick) = 0.01%, P (not sick) = 99.99%.
And then I don’t know how, but the value changed and became,
P(sick) = 1%
P(not sick) = 99% and so on.
I do not get this, is this some data issue, or is this issue with my understanding because I didn’t understand this, can anyone please help me out in this?
So the above image shows what we assumed and he changed the value to this -
Can someone explain how the percentage values changed in this?
