A clarification on the level of confidence for a Chi-squared distribution

Suppose we have${\chi}_{1-\alpha ,29}^{2}=45.22$ , where the Chi-squared distribution has 29 degrees of freedom and $(1-\alpha )\mathrm{\%}$ level of confidence. How then do we compute $1-\alpha$ ? The notation of $\chi}^{2$ . I've found in books and online sources all come in the form of $\chi}_{c}^{2$ , where c is the degrees of freedom.

I know this question seems trivial, but I'm still relatively new to Statistics.. Some clarification will be great!

For the 1s orbital of the Hydrogen atom, the radial wave function is given as: $R(r)=\frac{1}{\sqrt{\pi}}(\frac{1}{{a}_{O}}{)}^{\frac{3}{2}}{e}^{\frac{-r}{{a}_{O}}}$ (Where ${a}_{O}=0.529$ ∘A)

The ratio of radial probability density of finding an electron at $r={a}_{O}$ to the radial probability density of finding an electron at the nucleus is given as ($x.{e}^{-y}$). Calculate the value of (x+y).Find the sets $A$ and $B$ if $\frac{A}{B}=\left(1,5,7,8\right),\frac{B}{A}=\left(2,10\right)$ and $A\cap B=\left(3,6,9\right)$. Are they unique?
