No, it means it might, with a probability of 0.1
There is a 10% chance of any form of water falling from the sky.
Ten percent in precipitation typically refers to a forecast probability, indicating that there is a 10% chance of measurable rain occurring in a specific area over a defined period. It does not signify the actual amount of rainfall but rather the likelihood of precipitation happening. For example, if a weather report states a 10% chance of rain, it suggests that in similar weather conditions, rain would occur in 10 out of 100 instances.
There needs to be a location as well as a time interval. A statement such as "there is a 40% chance that it will rain in Yourtown over the 12 hours starting at sunrise tomorrow" means that if you consider a whole lot of days like tomorrow - with the same sort of weather as you experienced over the last few days - then in 4 days out of 10 (40%), it will rain tomorrow. Just to complicate matters, the statement does not distinguish between there being a 40% probability that it will rain non-stop or that it will rain briefly.
A forecast that says, for instance, "there is a 10% chance of rain tomorrow," means that on 10 out of 100 days with weather conditions very similar to the conditions expected tomorrow, at least a trace of train has occurred. Some will disagree with this answer for various reasons.

No because 1 out of 10 is 10%
A 30 percent chance of rain means there is a 3 in 10 chance it will rain in the specified area. It does not indicate the amount of rain that may fall, only the likelihood of precipitation occurring.
The current weather in Belgium is 50 degree's Fahrenheit. It is a 10 percent chance of rain. There is 94 percent humidity.

If there is a 40% chance of rain on Monday, 50% on Tuesday, and 40% on Wednesday then math tells us that there is a 82% chance of rain over those 3 days. Lately I have seen percentages listed for each hour of the day. For example, a 60% chance of rain for 7, 8, 9, 10, and 11 in the morning. Does that mean there is a 99% chance of rain that morning?

0.0001 percent chance out of 10
In Jewelry Stores .... 70% OFFat gas pumps... this fuel contains a 10% ethanol blendWeather predictions .... There's a 40% chance of rain today
No because 1 out of 10 is 10%
Mostly u get lucky but the chance is 16% most of the time
Forecasts issued by the National Weather Service routinely include a "PoP" (probability of precipitation) statement, which is often expressed as the "chance of rain" or "chance of precipitation".EXAMPLEZONE FORECASTS FOR NORTH AND CENTRAL GEORGIANATIONAL WEATHER SERVICE PEACHTREE CITY GA119 PM EDT THU MAY 8 2008GAZ021-022-032034-044046-055-057-090815-CHEROKEE-CLAYTON-COBB-DEKALB-FORSYTH-GWINNETT-HENRY-NORTH FULTON-ROCKDALE-SOUTH FULTON-INCLUDING THE CITIES OF...ATLANTA...CONYERS...DECATUR...EAST POINT...LAWRENCEVILLE...MARIETTA119 PM EDT THU MAY x 2008.THIS AFTERNOON...MOSTLY CLOUDY WITH A 40 PERCENT CHANCE OFSHOWERS AND THUNDERSTORMS.

SOUTHWESTWINDS 5 TO 15 MPH. CHANCE OF RAIN 40 PERCENT.What does this "40 percent" mean? ...will it rain 40 percent of of the time? ...will it rain over 40 percent of the area?The "Probability of Precipitation" (PoP) describes the chance of precipitation occurring at any point you select in the area.How do forecasters arrive at this value?Mathematically, PoP is defined as follows: PoP = C x A where "C" = the confidence that precipitation will occur somewhere in the forecast area, and where "A" = the percent of the area that will receive measureable precipitation, if it occurs at all.So... in the case of the forecast above, if the forecaster knows precipitation is sure to occur ( confidence is 100% ), he/she is expressing how much of the area will receive measurable rain. ( PoP = "C" x "A" or "1" times ".4" which equals .4 or 40%.)But, most of the time, the forecaster is expressing a combination of degree of confidence and areal coverage. If the forecaster is only 50% sure that precipitation will occur, and expects that, if it does occur, it will produce measurable rain over about 80 percent of the area, the PoP (chance of rain) is 40%. ( PoP = .5 x .8 which equals .4 or 40%. )In either event, there is a correct way to interpret the forecast: According to the NWS, "CHANCE OF RAIN 40 PERCENT" means there is a 40 percent chance that rain will occur at any given point in the area.NOTE! However, this is not entirely accurate language. It is better expressed as: "CHANCE OF RAIN 40 PERCENT" means the on average for all of the points in the area during the specified time period (usually 12 hour periods), chance that rain will occur (on average) is 40%.Explanation:Suppose the the forecast were for Maui, HI. One "given" point is your house near the top of Mt. Haleakala, where it rains almost constantly. 40% percent is obviously not accurate for that given point. So assume that Mt. Haleakala is 10% of the area of Maui and that the average chance of rain today there is 80%. And assume that the average chance of rain for the other 90% of the island is 35%. So for the entire island, the average chance of rain is (.9 * .35) + (.1 * .8) = .4 = 40%. Clearly, the smaller the area, the more meaningful and accurate "chance of rain" is.
