So Im pretty bad at science, Im learning radioactive decay in class and learned that after 2 half lives occur the parent daughter ratio is 1:3. The parent isotope is 25% and daughter 75%. Why isnt the ratio 1:4 after this?

Look up "ratios," you should probably review how they work.

The ratio of the parent to the TOTAL is 1:4. The ratio of the parent to the DAUGHTER is 1:3. There's a difference.

Thanks for the reply I sort of get it now, 1 is the parent and 3 is the daughter, and when added up equal to the total. im thinking of the parent to the total which is an entirely different expression

The probabilistic nature of decay makes it more or less a game of luck.

I think you mean deterministic*.

Yes it seems that way to us only because we can't comprehend what's happening at such a small level

Go back to the 1920s and take your pseudoreasoning and "epistemology only" with you.
