how to calculate p-value based on LRT values from chi-square distribution table

[Pooja Solanki]

For example

1).***********************************

LR = 2 (7573.81 - 7568.56) = 10.50

degrees of freedom = s-2 = 5-2 = 3

critical value (P = 0.05) = 7.82

here in example 1 how to check value  chi-square distribution table?

2)**********************************

likelihood ratio test statistic > 6.147; P < 0.01

In 2nd example how find p-value just based on LRT from chi-square distribution table?

If some one can explain me with an example, it would be a great help.
