kBinomial Distribution

u Binomial Probability

Binomial probability calculates a probability at a specified value for the discrete binomial distribution with the specified number of trials and probability of success on each trial.

f (x) = n C x px (1–p)n– x

(x = 0, 1, ·······, n) p : success probability

 

(0 <p <1)

 

n : number of trials

Perform the following key operations from the statistical data list.

5(DIST)

5(BINM)

1(Bpd)

The following shows the meaning of each item when data is specified using list specification.

Data ............................

data type

List ..............................

list whose contents you want to use as specified data

 

(List 1 to 26)

Numtrial .......................

number of trials

p ..................................

success probability (0 <p <1)

Save Res ....................

list for storage of calculation results (None or List 1 to 26)

Execute .......................

executes a calculation

The following shows the meaning of a parameter data specification item that is different from list data specification.

x ..................................

integer from 0 to n

After setting all the parameters, use c to move the highlighting to “Execute” and then press the function key shown below to perform the calculation.

• 1(CALC) ... Performs the calculation.
