To take it a step further, if that was the forecast 4 days in a row, you would expect it to rain one of those days.

Not necessarily.

There is a 0.750.750.75*0.75 or a 31% chance of no rain at all

I'm not saying it's certain, but it's what I'd expect. It raining on one day out of 4 is the most common case.
