# How to find the constant term in a probability density function

### How to find the constant c for the probability theory distribution density function ah, seek help from the schoolboys, thank you-

Simple calculations can be done, the answer is shown in the figure

### Probability theory distribution density function how to find the constant c ah,

(1). According to the definition of probability, the sum of the probabilities of all events occurring is one. So, integrating f(x) over x from 0 to 2 should result in 1.

The result of the integration is 8C/3. So C=3/8.

(2). All that is required is that f(x) integrates over x from 1 to 2, which is equal to 1/2.

### Find the constant of the density function?

According to the probability formula ∫(0 to 1)cx^adx=1 i.e. c/(a+1)=1 and EX=∫(0 to 1)cx^a*xdx=0.75 i.e. c/(a+2)=3/4 thus solving c=3,a=2

### How to find a constant for a college probability density and how to calculate the upper limit infinity

Where does the constant to be determined C come from? Is it in the probability density function? If so the probability density function from negative infinity to positive infinity of the integral = 1 using this relationship to solve for C this. I can’t read it lz can you write it down in a formula editor and upload it?

### Advanced Mathematics, Probability Statistics, How do you find the constant A in a distribution function of a continuous random variable when the distribution function is known?

F(x)=1 when x tends to positive infinity;

The derivative of F(x) integrates from negative infinity to positive infinity as 1;

b=1, a=-1.

For example:
