What is the sample space of rolling a number cube twice?
The sample space of a standard six sided die rolled twice, or two dice rolled once (they are the same) is [11, 12, 13, 14, 15, 16, 21, 22, 23, 24, 25, 26, 31, 32, 33, 34, 35, 36, 41, 42, 43, 44, 45, 46, 51, 52, 53, 54, 55, 56, 61, 62, 63, 64, 65, 66].
Find the sample space the find the indicated probability. Alana tosses 2 number cubes. She wins if she rolls double sixes. Find P(Alana wins.)?
The sample space is:11, 12, 13, 14, 15, 16, 21, 22, 23, 24, 25, 26, 31, 32, 33. 34, 35, 36, 41, 42, 43, 44, 45, 46, 51, 52, 53, 54, 55, 56, 61, 62, 63, 64, 65, 66. P(Alana wins) = 1/36 if the dice are fair.

Statistics HELP Electrical problems affect about 14 percent of new cars an automobile mechanic conducts diagnostic tests on 128 new cars. Describe the sampling distribution for the sample proportion?
Distribution would be centered at .14*128=17.92The standard deviation of the distribution would be root(n(p(p-1)))=root(128*.14*.86)=3.92571013Normal, unimodal
When taking a systematic random sample of size n every group of size n from the population has the same chance of being selected True or False?
False. A sample which contains two elements whose index value is smaller than the sampling increment will never be chosen. For example, if the increment is 5, then you could choose 1, 6, 11, ... or 2, 7, 12, ... or 3, 8, 13, ... or 4, 9, 14, ... or 5, 10, 15, ... but the sample comprising 1, 3, 4, ... cannot be chosen.
If you had a pair of fourteen sided dice what would be your sample space also what is the probability that the sum of the numbers is twenty?
Partial answer: Assuming that the dice show the numbers 1, 2, 3, ... 14 on each die, and that the question refers to throwing both dice and getting the sum. The smallest sum is 2 and the greatest sum is 28. So the sample space is 2,3,4,...,28.

How does carbon dating work ma?
Carbon dating works by measuring the amount of radioactive carbon-14 in a sample. Carbon-14 is present in all living organisms and decays at a known rate after death. By comparing the amount of carbon-14 remaining in a sample to the amount in living organisms, scientists can determine the sample's age.

Does a small sample of Carbon-14 have the same activity as a large sample of Carbon-14?
No and yes. It depends on the way you define activity. Carbon-14 undergoes radioactive beta decay. The activity of Carbon-14 is given in terms of disintegrations per minute per gram of carbon. So, if you have a 100 gram sample and a 1 gram sample, there will be 100 times more disintegrations per minute with the larger sample. But typically, we are more interested in the time it takes a certain percentage to decay. Time values like half life will be the same for large and small samples.
The half life of carbon 14 is 5730 years If a 1g sample of old carbon is one eighth as radioactive as 1g of a current sample then the age is about?
The ratio of radioactive carbon-14 in the old sample to the current sample is 1:8, suggesting 3 half-lives have passed. Since each half-life is 5730 years, the age of the old sample would be approximately 17190 years.
Can carbon dating be used on bones a million years old?
No, there are no detectable levels of carbon-14 left in any sample older than roughly 40,000 years. Without carbon-14 in the sample, no date can be determined.
