Answer
Small.
Work Step by Step
The degree of freedom is the number of rows minus one multiplied by the number of columns minus one, hence: $df=(r-1)(c-1)=(4-1)(2-1)=3$.
The P-value can be obtained from the row $df=3$ containing the value $X^2=99.6058$, thus $P\lt0.0005$. Thus the result of SAS is even more precise than the result of the table but what is common is that both of them are very small.
