<math>\frac{(oi-ei)^2}{ei}</math>         0.668                        2

The <math>\chi^2</math> value is 2.668

The x^2 value is 2.668

Now <math>df=(r-1)(c-1) = (2-1)(2-1) = 1 </math>

Now df=(r-1)(c-1)=(2-1)(2-1)=1

From the Chi Squared Distribution probability table with <math>df</math> is 1, the <math>\chi^2</math> value of 2.668 is  0.10.

From the chisquared distribution probability table with df is 1 for the X^2 value 2.668 is  0.10.
