Trials is the number of independent trials.
Valor p: a probabilidade de éxito de cada ensaio.
T1 defines the lower limit for the number of trials.
T2 (optional) defines the upper limit for the number of trials.
Exemplo
What is the probability with ten throws of the dice, that a six will come up exactly twice? The probability of a six (or any other number) is 1/6. The following formula combines these factors:
=B(10;1/6;2) returns a probability of 29%.
BINOM.INV
Returns the smallest value for which the cumulative binomial distribution is greater than or equal to a criterion value.
Sintaxe
BINOM.INV(Trials; SP; Alpha)

Valor p: a probabilidade de éxito de cada ensaio.

Exemplo
=BINOM.INV(8;0.6;0.9) returns 7, the smallest value for which the cumulative binomial distribution is greater than or equal to a criterion value.
CHISQDIST
Returns the probability of a deviance from a random distribution of two test series based on the chisquared test for independence. CHISQ.TEST returns the chisquared distribution of the data.
The probability determined by CHISQ.TEST can also be determined with CHISQ.DIST, in which case the Chi square of the random sample must then be passed as a parameter instead of the data row.
Sintaxe

DataB is the array of the observations.
DataE is the range of the expected values.

=CHISQ.TEST(A1:A6;B1:B6) equals 0.0209708029. This is the probability which suffices the observed data of the theoretical Chisquare distribution.
CHISQDIST
Returns the probability density function or the cumulative distribution function for the chisquare distribution.
Sintaxe
CHISQ.DIST(Number; DegreesFreedom; Cumulative)
Number is the chisquare value of the random sample used to determine the error probability.
DegreesFreedom are the degrees of freedom of the experiment.
Cumulative can be 0 or False to calculate the probability density function. It can be any other value or True to calculate the cumulative distribution function.
Exemplo
=CHISQ.DIST(3; 2; 0) equals 0.1115650801, the probability density function with 2 degrees of freedom, at x = 3.
=CHISQ.DIST(3; 2; 1) equals 0.7768698399, the cumulative chisquare distribution with 2 degrees of freedom, at the value x = 3.
CHISQDIST
Returns the probability value from the indicated Chi square that a hypothesis is confirmed. CHISQ.DIST.RT compares the Chi square value to be given for a random sample that is calculated from the sum of (observed valueexpected value)^2/expected value for all values with the theoretical Chi square distribution and determines from this the probability of error for the hypothesis to be tested.
The probability determined by CHISQ.DIST.RT can also be determined by CHITEST.
Sintaxe
CHISQ.DIST.RT(Number; DegreesFreedom)
Number is the chisquare value of the random sample used to determine the error probability.
DegreesFreedom are the degrees of freedom of the experiment.
Exemplo
=CHISQ.DIST.RT(13.27; 5) equals 0.0209757694.
If the Chi square value of the random sample is 13.27 and if the experiment has 5 degrees of freedom, then the hypothesis is assured with a probability of error of 2%.

Sintaxe

X é o valor no cal a función será calculada.

Cumulative (optional): 0 or False calculates the probability density function. Other values or True or omitted calculates the cumulative distribution function.

Exemplo
A die is thrown 1020 times. The numbers on the die 1 through 6 come up 195, 151, 148, 189, 183 and 154 times (observation values). The hypothesis that the die is not fixed is to be tested.
The Chi square distribution of the random sample is determined by the formula given above. Since the expected value for a given number on the die for n throws is n times 1/6, thus 1020/6 = 170, the formula returns a Chi square value of 13.27.
If the (observed) Chi square is greater than or equal to the (theoretical) Chi square CHIINV, the hypothesis will be discarded, since the deviation between theory and experiment is too great. If the observed Chi square is less that CHIINV, the hypothesis is confirmed with the indicated probability of error.
=CHISQ.INV.RT(0.05;5) returns 11.0704976935.
=NORMSINV(0.908789) devolve 1,3333.
If the probability of error is 5%, the die is not true. If the probability of error is 2%, there is no reason to believe it is fixed.
COUNT

Value1; Value2, ..., Value30 are 1 to 30 values or ranges representing the values to be counted.
Exemplo
The entries 2, 4, 6 and eight in the Value 14 fields are to be counted.
=COUNT(2;4;6;"eight") = 3. The count of numbers is therefore 3.

Sintaxe
COUNTA(Value1; Value2; ...; Value30)
Value1; Value2, ..., Value30 are 1 to 30 arguments representing the values to be counted.

Sintaxe
COUNTIF(intervalo;criterio)
Faixa é o intervalo ao cal os criterios deben ser aplicados.
Criteria indicates the criteria in the form of a number, an expression or a character string. These criteria determine which cells are counted. If regular expressions are enabled in calculation options you may also enter a search text in the form of a regular expression, e.g. b.* for all cells that begin with b. If wildcards are enabled in calculation options you may enter a search text with wildcards, e.g. b* for all cells that begin with b. You may also indicate a cell address that contains the search criterion. If you search for literal text, enclose the text in double quotes.
Exemplo
A1:A10 is a cell range containing the numbers 2000 to 2009. Cell B1 contains the number 2006. In cell B2, you enter a formula:
=COUNTIF(A1:A10;2006)  this returns 1.
=COUNTIF(A1:A10;B1)  this returns 1.
=COUNTIF(A1:A10;">=2006")  this returns 4.
=COUNTIF(A1:A10;"<"&B1)  when B1 contains 2006, this returns 6.
=COUNTIF(A1:A10;C2) where cell C2 contains the text >2006 counts the number of cells in the range A1:A10 which are >2006.
Para resumir só números negativos: <item type ="entrada"> = SUMIF (A1: A10;"<0") </ item>
