There are many frequency distributions:
Uniform, Binomial, Multinomial, Poisson, Gaussian, Chi-square, Student's t, Fisher's F, Beta, Gamma, Lognormal, Logistic to name some off the top of my head. And I am sure I've missed many more.
You need to specify which ones you are interested in.
Forgot the Exponential.

Are outcomes in binomial distributions dependent on each other?
No.
What is the shape of each distribution in a data set?
The distributions can have any shape that you like.
How many types are there of frequency distribution?
Introduction:Frequency distribution is used to compress and summarize the whole data by grouping the data into classes and records the data points that fall in each class. The frequency distribution is considered as the base for descriptive statistics and they are also used to define the ordinal, nominal and the interval data. Frequency distribution is the comfortable way of grouping and organizing the data.Example of Frequency Distribution:Consider the frequency table for the students in a class where the data has been grouped according to the height of the students. Range of height Total number of student's cumulative frequency3.0 - 4.5 feet 15 154.5 - 5.0 feet 20 355.0 - 6.5 feet 25 506.5 - 7.0 feet 30 80In the case of nominal data the use of the contingency table is required. The frequency distributions are used to present the data graphically.Types of Frequency Distributions:There are three types of frequency distributions. Cumulative frequency distribution,Grouped frequency distribution,Cumulative Grouped frequency distribution.Cumulative frequency distribution (type 1):The cumulative frequency can be found from the frequency distribution by adding the cumulative frequency column. The highest cumulative frequency should be equal to the total number of frequenciesTemperature Frequency Cumulative frequency47 3 2246 3 1945 4 1544 3 1243 3 9Grouped frequency distribution (type 2):The grouped frequency distribution can be formed by grouping the values together into the class intervals.

What is the frequency in a frequency table?
The frequency in a frequency table is the number of occurrences within each class width. The total frequency is the sum of all frequency's within all the classes.
How do frequency and period relate to each other?
Frequency and period are mutual reciprocals.
What is a frequency distributions?
The frequency distribution shows in a graph or a table all the possible values of a variable, called the random variable, and the frequency or the count of each value. For example, if you had the ages of 100 people you could do a frequency distribution and split the ages into 10 year categories and then show how many of the 100 people were in the 20s, how many in their 30s, how many in their 40s and so on.
Are outcomes in binomial distributions dependent on each other?
No.
What should a well constructed histogram reveal to you?
It should reveal the frequency density of the variable for the well-defined classes. From this, it should be easy to work out the exact frequency in each class.
What are the three basic components to a fitness program and the necessity for each component?
frequency, intensity and time
What is the shape of each distribution in a data set?
The distributions can have any shape that you like.
Investment Distributions?
Investment Distributions This calculator helps you determine either how large or how long periodic distributions can be taken out of an investment before it runs out. If you enter the number of years you need the distributions to last, this calculator determines the amount you can take out each period. If you enter a periodic distribution, it will calculate how long before your balance runs out.
What is best used for displaying frequency distributions when one or two categories make up a large proportion of the total?
a bar graph is best. If it's two categories make sure you have different colors/pattern to differentiate between the two categories. You should also include a key to tell you what each color/pattern representsBar chart
Frequency of mobile computing?
Each frequency will differ with each mobile device. Frequency is known as the number of times at which an electromagnetic wave oscillates per second.

What lists the frequency of each item in a data set?
frequency table
How does the energy of three photons of blue light compare with that of one photon of blue light from the same source?
If the color (frequency, wavelength) of each is the same, then each photon carries the same amount of energy. Three of them carry three times the energy that one of them carries.
What is the frequency in a frequency table?
The frequency in a frequency table is the number of occurrences within each class width. The total frequency is the sum of all frequency's within all the classes.
