What is the probability of when you roll a dice you will get a higher number than the number you got the last you rolled the dice?

5/12

Consider the possibile outcome of two rolls of a die (where order matters):

(1,1)

(1,2)

(1,3)

.

.

.

(4,6)

(5,6)

(6,6)

There are 6*6=36 possible outcomes. Of these, the following would achieve the result desired:

(1,2)

(1,3)

(1,4)

(1,5)

(1,6)

(2,3)

(2,4)

(2,5)

(2,6)

.

.

.

(5,6)

For the first die equal to 1, there are 5 successful results. For the first die equal to 2, there are 4 successful results....For the first die equal to 5, there is 1 successful result. The total number of successful outcomes=5+4+3+2+1.

So the probability that the desired outcome is obtained=(5+4+3+2+1)/36=15/36=5/12.

A standard dice is rolled 10 times withthe out come 2 1 3 2 5 1 0 in this order you can you make it where it is less or equal to 8?

The lowest number I can roll on a die is 1.

In ten rolls, that's a minimum of ten; I cannot make it 8 or less.

Zero is a foul throw.

Solutionsn of Moment-generating functions?

Your question did not identify one distribution in particular. I have provide in the related link the moment generating functions of various probability distributions.

How many combinations of three out of thirty one?

If the sequence of the three makes a difference, there are (31 x 30 x 29) = 26,970.

If the sequence of the three doesn't matter, there are (31 x 30 x 29) / (3 x 2 x 1) = 4,495.

Whatr does the number 30 mean?

The number 30 is one more than 29 and one less than 31, it is also 6 lots of 5, 3 lots of 10 or 2 lots of 15

What is the median of 10 13 14 27 35 42?

There are six numbers, so the median is the mean of the third and fourth (when ordered).

Median = (14+27)/2 = 41/2 = 20.5

What does current research indicate about narcolepsy?

Researchers are hopeful that new treatments will releive the genetic mutation. Also, a number of drugs are being tested to improve daytime sleepiness.

What is the relevance of probability and statistics in the field of information technology?

In the field of IT you are dealing with probabilities all day long. How long will the hardware last, how can you keep the signal for the network strong all over the building, how will adding a new group of computers impact the network, or heaven forbid your network come under attack and you need to keep damage to a minimum while fending off the attack. IT professionals think in probabilities. They're always running scenarios through their heads to come up with and fix problems before they occur.

What rhymes with skew?

stew, spew, screw, chew, woo, moo, too, true

What is the largest three digit number using numerals 4 and 8?

Using only 8's & 4's and using each atleast once...884. Using all numerals and including 8 once and 4 once...984.

What do you do if your doing mean medain and mode and you have four numbers as your mode what do you do?

It is acceptable (and quite common) to have multiple values for the mode.

Examine the following data sample:

Number of pets per family on Main Street

1,1,1,1,1,2,2,2,2,2,3,3,3,4,4,5,9

In this case, the mode is {1, 2}

What is the definiton of a median?

irdk and irdc and all you gotta do is put ur finger down lmfao

Why would someone want to assume that your sample data represents a population distrubution?

Most people take samples so that they may make estimates of parameters of interest: mean, variance, etc for the whole population. For such an estimate to have any validity the sample data must be assumed to represent a population distribution. Otherwise any conclusions based on the sample are valid only for the sample: hardly worth the effort!

Is sociology more than statistics?

Sociology is the study of human behavior in a social environment and how social interaction relates to development of mental and physical abilities, as well as future success and failure. Statistics are near irrelevant to sociology because it is a very intuitive field of study. So yes, sociology is much more than statistics.
