The simplest - and not very useful - method is to establish how many days in the year it rains or snows. Then that number, divided by 365 (or 365.25) is the probability that it will rain or snow on a given day.
You can improve on that estimate by considering data for only the days on which it rained or snowed during the relevant month in previous years. Further refinement can come from looking at what the weather was like on the previous day, previous 2 days and so on. Yet another improvement is to look at what is happening upwind from your location. Each refinement requires more information to be processed but improves your forecast. The trade-off is reached when the marginal cost and time spent in collecting and processing any additional data is just equal to the marginal benefit obtained from an improved forecast.
The chances that it will rain or snow at a given time.
False; the "or" is an additive property so the probability of rain or snow muse be greater than or equal to 0.65.
There is insufficient information in the question to properly answer it. The probability of snow at any given time depends on location, which you did not give. Please restate the question.
A certain event is any event that will definitely happen. For example, the sunrise tomorrow is something that is certain to happen (although it might be obscured from view by rain, snow, fog or something else); this will certainly happen.
The water equivalent of snow varies, but as a general rule, 20 centimetres of freshly fallen snow is equivalent to 2 cm of rain. If the snow has been lying around for a while then its density will increase.

If you mean 43%, then the probability that it will not snow is 57%, 0.57 or 57/100.
Precipitation
There is no direct conversion between rain and snow because the amount of snow that is produced from a given amount of rain can vary greatly depending on factors such as temperature and humidity. On average, 10 mm of rain is roughly equivalent to 1 cm of snow. So, 3 mm of rain could potentially produce around 0.3 cm of snow.
Precip is an abbreviation of precipitation, which means anything that falls from the sky, such as rain, snow, hail, sleet, etc. The chance of precipitation is a weather report which tells you how likely it is that the day's weather will include rain, snow, etc.
Seattle, Washington
Precipitation potential refers to the likelihood or probability of precipitation occurring in a specific area within a given timeframe. It takes into account various meteorological factors such as humidity, temperature, and atmospheric dynamics to estimate the chances of rain, snow, or other forms of precipitation.
The 4 main precipitaions are rain, hail, sleek and snow
The name for the release of condensed matter back to the ground in the form of sleet, snow, hail, or rain is precipitation.
No, snow and rain are two different forms of precipitation. Snow falls as frozen ice crystals, while rain falls as liquid water droplets. Snow forms when the temperature is cold enough for water vapor to freeze before it reaches the ground, whereas rain forms when water droplets combine and fall from clouds.
