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
The probability of rain on any given day is independent of the previous day, assuming that weather conditions do not influence each other. Therefore, to calculate the probability of rain on two consecutive days, you would multiply the individual probabilities of rain on each day. For example, if the probability of rain on any given day is 30%, the probability of rain on two consecutive days would be 0.30 * 0.30 = 0.09 or 9%.
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.
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
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.
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.
