It is 5C3*(1/2)3*(1/2)2 = 10/32 = 5/16
20% first day, 40% second day, Total percent of rain over the two days is (20+40)/2 = 30% per day
P(Rain) = 0.4 P(No Rain) = 0.6 P(Rain on 3 out of 5 days) = 5C3x(0.6)^2x(0.4)^3 = 0.2304 P(Rain on 4 out of 5 days) = 5C4x(0.6)^1x(0.4)^4 = 0.0768 So P(Rain 3 or 4 out of 5 days) = 0.2304 + 0.0768 = 0.3072
No. There is a 60% chance that on a given day there will be no rain at a given location in the forecast area. But for two days that reduces to 36% ( .6x.6), and to 21% (.6x.6 x.6 ) for three days, etc., based on probability.
No, 40% chance of rain is How Likely it is to rain for that day,or week. Not Area. LOL
The forecast didn't say "100 percent rain". It said "100 percent chance of rain".That means that the conditions that cause rain are so perfect that you can besure of it, and there's no question: It's definitely going to rain.
In 2008, Kansas City had 80 days with measurable precipitation.
20% first day, 40% second day, Total percent of rain over the two days is (20+40)/2 = 30% per day
It means there is a 5% chance of rain for the given day. If you were presented with 100 days of equivalent conditions, you would expect it to rain for 5 of them

The wettest US City is Hilo Hawaii which averages 128 inches of rain each year and has 277 rain days. Yuma Arizona averages 2.65 inches to rank as the driest City and has 17 rain days each year.
The percentage of rain days on Aruba averages around 17 percent. The yearly average number of days with measurable preciptation [greater than 0.4 inches] is 62 days. The months with the greatest number of rain days are October [6.7 days], November [9.7 days], and December [10.5 days].For more Aruba weather averages, please visit the link provided below.
To find the probability that it will rain both today and tomorrow, you multiply the individual probabilities: 0.60 (chance of rain today) * 0.40 (chance of rain tomorrow) = 0.24 or 24%. Therefore, there is a 24% chance that it will rain both today and tomorrow.

A 40 percent chance of rain means that there is a probability of 40 percent that it will rain. It is not a guarantee that rain will occur, but rather an estimation of the likelihood.
IF probability of rain is X percent then probability of no rain is 100- X percent. For example if prob of rain is 80% prob of no rain is 20%
A coastal city located in a region with a rainy climate, such as Seattle in the Pacific Northwest, would likely experience more days of rain compared to a coastal city in a region with a dry or arid climate, such as Los Angeles in California.
