so you're saying there's a 90% chance it will rain at any given point in 12 hrs? that seems high, but plz prove me wrong i like to learn


The idea is: if it doesn't rain the first hour (60% chance) it might rain the second hour (60%), or the third (60% chance), etc for 12 hours.

It will obviously be pretty high, but idk the equation

Yes!! ;)

I'm trying to explain it to these people that it would be pretty high, but they're trying to say it's going to be 60% <_<

I'm guessing it to be around 98%, but I don't know the equation.

Yeah, this thing seems to think it's around 99.96?

For the next 12 hours there is a 60% chance to train every hour.

What is the chance that it rains at any point during those 12 hours?

/E I need an equation :)

Oh, duh, it really is simple math. Find the probability of it not happening, then take that to the 12th power and subtract from 1.

.4^12 = 0.00001677721, which gives a 0.99998322278 aka 99.998322278% chance.

I do not understand the correlation between your training schedule and the chance of precipitation

The problem statement is too ambiguous.

Is it a 60% chance that all 12 hours contain rain, or is there a 60% chance of rain for each individual hour in the next 12 hours.

what is the point of trying to figure out the chance of a single rain drop falling in a 12 hour span? How is this information useful? Are we doing your school work?

50% chance, either it happens or it doesnt.
