Lambda is a measure of association for nominal variables. It is calculated as (E1 - E2) / E1, where E1 is the number of errors made when predicting the dependent variable without knowing the independent variable, and E2 is the number of errors made when predicting the dependent variable knowing the independent variable. In this table, E1 = 500 (the total number of people who don't attend church), and E2 = 450 (the number of people who don't attend church when gender is known). Lambda = (500 - 450) / 500 = 0.10, which is closest to 0.22 among the given options.
