### 5/5 — Great functionality

*2022-11-14*

It’s very easy and convenient to use. I would strongly recommend this app if you like to use Bayes theorem to calculate probability.

### 4/5 — Confusion

*2022-11-07*

I’m learning this math and using your calculator to help; please, what is the specific equation this calculator uses?

I’m used to P(A|B)=[ P(B|A) * P(A) ] / P(B)

But unfamiliar with adding P(B|-A) or how the calculator is using that information

Thank you!

(Four stars for now because there’s no description or explanation in settings)
