Weather percentages for rain.
I was just wondering about the 5 day extended weather forcasts in The Daily Sun and I hope someone will come up with a good answer for my question.
I know that when you flip a coin the chance of getting heads or tails is always 50%. So even if you flip ten heads in a row, the eleventh flip will still represent a 50% chance for heads or tails.
But is the weather the same? I know it seems like a dumb question, but hear me out.
Suppose you have a five day extended forcast that predicts a 50% chance of rain on Monday but a 0% chance for (each day) the rest of the week.
Then compare it with this forcast: A 50% chance of rain for each day for Monday through Friday. This means there could be no rain at all for the whole week or it could rain every day. Both scenarios are possible.
What is the percentage chance of rain for each week as a whole?
