Any mathfags here? Can you calculate a probability for me.

One of my stocks gain/loss % since i bought it was at exactly 17.00% Friday. Friday also was on the 17th. The gain is shown to up to 2 decimal points.

Is it 1/100 * 1/100 * 1/30 = 0.000005. Or 0.0005% probability? Is that math correct? How do i convert that into odds, like "1 in 281,282,448"
