u knw how to find the degrees of freedom and the chi-squared value right?
so the degrees of freedom re two and the chisquared value is 39.9,look at the values for the degrees of freedom in the table, 39.9 is greater than 13.82 which is the highest corresponding value for 2 degrees of freedom.Hence, 0.001 which corresponds to 13.82 in the table is the probability of the chisquaredvalue.
Hope this helps.im not particularly good at explaining.
