I've already stated the correct answer and it isn't exactly 1/3.

Please show the exact calculation you did.

Here's the first line mine: $\frac{(0.95)(0.005)}{(0.95)(0.005) + (0.01)(0.995)}$.

2. I eventually got what you got, my calculator has predictive fractions still on from when I was doing approximating fractions for irrational numbers, sorry about this
