The probability is 1.
It is always raining - any time of the day or night, any day of the year - somewhere on Earth.
There is a 70% chance it will not rain tommorrow! There is a 70% chance it will not rain tommorrow!
Certain.
There is insufficient information in the question to properly answer it. You need to specify what range of dates and what the typical climate is like, perhaps by specifying the geographic location that you are interested in. If you want to take this to an extreme, and say for any date and for anywhere on the world, then since it is always raining at least somewhere, then the probability that there will be rain during at least one of three days is 1.
In a family with four children, the probability of having four boys is 1 in 16.
There is an 80% or 0.80 chance that it will not rain on Saturday
If the probability that it will rain is 0.25, then the probability that it is sunny is 0.75. The probability of it being sunny for five days, then is 0.755, or about 0.2373.
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
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%
The probability is 1. At any point in time it is raining somewhere on earth.
The probability that it will rain today and tomorrow is the multiplication of the probabilities of it raining both days. That is 0.6 X 0.4 = 0.24 So there is a 24% chance that it would rain both days.
That depends on where you are. Think about if you are in the Namibian desert or in a tropical rainforest
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
LetA= rainP(A)=0.38LetA'= not rainP(A') =1 - P(A)=1 - 0.38=0.62so probability of it will not rain tommrow is 0.62
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 a high probability of rain this evening."
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.
Probability is the study of chance or the likelihood of an event happening. Directly or indirectly, probability plays a role in all activities.For example, we may say that it will probably rain today because most of the days we have observed were rainy days. However, in mathematics, we would require a more accurate way of measuring probability.
