CHIDIST(x,df)

This function gives the one_tailed probability of the chi-squared distribution.
It is denoted by $\chi ^{2}$ distribution.
Normally categorical data's may displayed in tables.
The $\chi ^{2}$ static used to compare the observed value in each table to the assumed value.
The conditions of $\chi ^{2}$ test is

$\chi ^{2}=\sum {\frac {(Oi-Ei)^{2}}{Ei}}$

The degrees of freedom are: Failed to parse (syntax error): {\displaystyle (r–1)(c–1)}

Where:

Also this function will the result as Error when
