If there is a 30 chance of sun tomorrow and a 20 chance of wind and no sun what is the probability that it is windy given that it is not sunny Round your answer to the nearest percent A57 B44 C22 D29?
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%
What is the probability of 2 or more people in a a group of about 30 having the same birthday?
The probability with 30 people is 0.7063 approx.
If you draw a card from a normal deck of cards what is the probability the card is either a red or a jack?
The chance it is red is 1/2 The chance it is a jack is 4/52 Now add the two together: 1/2 +4/52 = 30/52 However this double counts the jacks that are red 2/52 so 30/52 - 2/52 = 28/52 Therefore the probability you draw a jack or a red is 7/13
What is prior classical probability?
When you throw a die, there are six possibilities. The probability of a number from 1 to 6 is 1/6. This is classical probability. Compare this with empirical probability. If you throw a die 100 times and obtain 30 sixes, the probability of obtaining a 6 is 30/100 or 0.3. Empirical probabilities change whereas classical probability doesn't.
The probability that an individual is left handed is 0.1 In a class of 30 students what is the probability of finding at least 5 left hander's?
This is a binomial probability distribution. The number of trials, n, equals 30; and the probability of success is p, which is 0.1. In this problem, you want the probability of at least 5, which is the complement of at most 4. We use the complement because we can subtract from 1 that probability and we will have the solution. The related link has the binomial probability distribution table which is cumulative. Per the table, at n=30, p=0.1 and x = 4; the probability is 0.825. Therefore the probability of at least 5 is 1 - 0.825 or 0.175.
If there is an 80 percent chance of rain and a 30 percent chance of wind and rain what is the probability that it is windy given that it is rainy Round your answer to the nearest percent.?
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%
Percent chance of rain?
A forecast that says, for instance, "there is a 10% chance of rain tomorrow," means that on 10 out of 100 days with weather conditions very similar to the conditions expected tomorrow, at least a trace of train has occurred. Some will disagree with this answer for various reasons. For the results of research that evaluated how understanding of percentage chance of precipitation varies around the world, see "A 30% Chance of Rain Tomorrow: How Does the Public Understand Probabilistic Weather Forecasts?," available as a PDF file via the URL http://www.mpib-berlin.mpg.de/en/mitarbeiter/gigerenzer/pdfs/RainFinal.pdf .

Can probability be higher than 100 percent... Say you have 4 oil wells each with a 30 percent chance of hitting ...Isn't the calculated probability of one hitting 120 percent?
No. Probability is defined as a number between 0 and 1 (100 percent). If you have four oil wells, each with a probability of hitting being 30%, then the probability of at least one hitting is 100% - (100% - 30%)4, or about 76%.
