P(R) = 0.7
The correct choice of answer is B. 71%.
It is 67%.
78% I just had this question on apex
0.20 + 0.80*0.80
There is a 70% chance it will not rain tommorrow! There is a 70% chance it will not rain tommorrow!
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
It is 67%.
78% I just had this question on apex
0.20 + 0.80*0.80
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.
There is a 70% chance it will not rain tommorrow! There is a 70% chance it will not rain tommorrow!
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
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%
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%
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.
A thirty percent chance is a low probability, so it probably won't rain, but it could.
