Pr(Windy given not Sunny) = Pr(Windy and not Sunny)/Pr(not Sunny)
= 0.2/(1 - 0.3) = 0.2/0.7 which rounds to D 29%
It is 67%.

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.
To find the probability of it being windy given that it is not sunny, we can use conditional probability. The probability of it being not sunny is 70% (100% - 30% chance of sun). The probability of it being windy and not sunny is 40%. Therefore, the probability of it being windy given that it is not sunny is ( P(\text{Windy | Not Sunny}) = \frac{P(\text{Windy and Not Sunny})}{P(\text{Not Sunny})} = \frac{40%}{70%} \approx 0.57). Rounding to the nearest percent, the probability is approximately 57%.
There is a 70% chance it will not rain tommorrow! There is a 70% chance it will not rain tommorrow!
To get the answer to this question you need to work out what 30% of 80% is. To do this you need to divide 30, by 80, then multiply your answer by 100. 30/80=0.375, 0.375*100=37.5, 37.5 to the nearest percent is 38%
It is 1 - prob(it does not rain today and tomorrow)= 1 - prob(it does not rain today)*prob(it does not rain tomorrow) = 1 - [1- prob(it does rain today)]*[1 - prob(it does rain tomorrow)] = 1 - [1 - 0.8]*[1 - 0.5] = 1 - 0.2*0.5 = 1 - 0.1 = 0.9
My answer for probability Probability is the chance that something will happen - how likely it is that some event will happen. Sometimes you can measure a probability with a number: "10% chance of rain", or you can use words such as impossible, unlikely, possible, even chance, likely and certain. Example: "It is unlikely to rain tomorrow".
Probably not
probably a 93 percent chance.
