A computer cannot truly generate a random number because it needs a seed value. The system time is a good source for random numbers because it generates a random number every second. If you execute a program with a button that generates a random number based on the system time, every time you click the button it will generate a different number (assuming you didn't press it twice in the same second) because it changes second by second. Although, it seems that the system is generating a random value by using the system time, it really isn't. It is just using the specific time value as a seed.
Stochastic process is also known as a random process. It is a collection of random variables that represent the evolution of some system of random values over time.
Using random method create the random number and save that in to Database
A random variable is a variable which can take different values and the values that it takes depends on some probability distribution rather than a deterministic rule. A random process is a process which can be in a number of different states and the transition from one state to another is random.
Yes.
A random variable which can take qualitative values rather than numeric values. For example, the question "What colour are your eyes?" will generate qualitative answers.
continuous random variable
Data from random samples will not always include the same values. Values are chosen randomly and they may or may not be the same. So means will vary among random samples.
A random variate is a particular outcome of a random variable: the random variates which are other outcomes of the same random variable would have different values.
It can take only a finite number of values. These need not be integer values.
the range of values of a random variable.
A bit is a binary digit that is the second smallest increment of data on a computer. It can hold only two values which are 0 and 1.
In it's simplest terms, a computer is actually a digital binary system. It is a very large number of containers or "bits" which are either numbered one ( for on) or zero (for off). As an electrical charge stores these alternating bit values, it is a digital system.
