income over $55,000 475 375 850
income below $55,000 75 75 150
total 550 450 1,000
based on these data, are "being male" and "earning over $55,000" independent events?
no, p(being male | the person earns over $55,000) ≠ p(being male)
no, p(being male | the person earns over $55,000) = p(being male)
yes, p(being male | the person earns over $55,000) = p(being male)
yes, p(being male | the person earns over $55,000) ≠ p(being male)
