Probability
The probability of a certain event is a number expressing the likelihood that a specific event will occur, expressed as the ratio of the number of actual occurrences to the number of possible occurrences. In mathematics, it is a measure of how often an event will happen and is the basis of statistics.

Whats the volume of a standard deck of cards?
0.75 inch thick * 2.5 inch wide * 3.5 inch long = 4.37 inch^3 = 71 mL
1.9cm thick * 6.4 cm wide * 8.9 cm long = 108.2 cm^3
Explain probability distribution?
A probability distribution describes the likelihood of different outcomes in a random experiment. It shows the possible values of a random variable along with the probability of each value occurring. Different probability distributions (such as uniform, normal, and binomial) are used to model various types of random events.

Why did Mendel study such a large sample of pea plants to determine the probability of inheritance?
The more samples you use, the closer your results will match probability.
What does DX Error 0x8876086c mean?
Unfortunately error codes returned by DirectX rarely mean anything. The developers show extreme laziness in this regard. The only way you are going to get any information about your problem is via running DirectX in Debug mode with diagnostics output turned on. The diagnostics text is actually very useful.
D3DERR_DRIVERINVALIDCALL = MAKE_D3DHRESULT(2157) = 0x8876086c = -2005530516 is defined in "d3d9.h"

How do you get a replacement national insurance card without calling the UK from Germany?
Unfortunately this is not possible.
I had the same problem about ten years ago.
The Department of Work and Pensions in Newcastle, are the only people that have the authority to issue a replacement.
How do you compute probabilities of a standard normal random variable?
You need to determine the area under the curve between the values in question. This is easy to do because there are tables that give the area values.
When two dice are rolled find the probability of getting a sum less than 4 or greater than 9?
Here are the ways of rolling the dice that satisfy those conditions:
1 1
1 2
2 1
4 6
5 5
5 6
6 4
6 5
6 6
There are nine possibilities out of 36, hence, the probability is 9/36 = 1/4.
What is the probability of a couple having four children in the following order girl girl girl boy?
It is not possible to answer the question because:
- the total number of children that the couple had is not known;
- the gender of the child depends [mainly] on the father, and is not 0.5;
- the gender of each child is not independent of the gender of previous children.
How do we calculate probability from bivariate normal distributions?
A calculator for the Bivariate Normal
At the bottom of the page at the link, under "A calculator for cumulative probabilities from the bivariate normal distribution" there's a little binary applet, which can be downloaded, and which calculates the percentage chances of being in various parts of the volume of the distribution.
What do experimental probability and theoretical probability have in common?
They are both measures of probability.
"netiquette" is a word formed from the words "net" or internet and "etiquette." It means the rules that are followed for conversation online to be socially acceptable. This might include something like "don't type in all capitals. This makes it look like you're shouting" and other such rules specific to online conversations. Normal etiquette and social rules from real life still apply online, in addition to netiquette.
What is the probability that the sum of the two dice is less than 5 or exactly 9?
The relevant rolls are 11, 12, 13, 21, 22, 31, 45, 54, 36, 63, - 10 rolls out of 36, or 27.8%.
May 8th, 1945 is known as Victory in Europe Day (VE Day) because on that day the Allies accepted Germany's unconditional surrender at the close of WW2.
Why is the study of genetics important?
Genetics are important to study because it helps us figure out traits of things to help find genetic disorders.
What is the probability of rolling a number greater than 2 on a number cube?
its is likely 2/3 or 1/6
What is the probability of one person in a random group of fifty people having a birthday today?
About a 12.8 percent chance. The math is actually very simple: q(n)= 1- (364/365)n Where "n" is the number of people present. It is worth noting that in a room of 50 people, there is a 97% chance that two of them share the same birthday.
Where can you see a drawing of how a deck belt goes on a model 3410 with 42 inch deck?
You will need to order a manual on the mower from the manufacturer (I assume Simplicity).
What is the probability of tossing a numbre less than 3 on a number cube labeled 1 to 6?
The probability of tossing a 1 or 2 on a six sided die is 2 in 6, or 1 in 3.
