Without the border,a flower bed measures 4.5 m by 3 m. the width of the border frame is .5 m on all sides. how much space will the garden take up in the yard?

I got 1738 but im not sure if that is correct 

                                               Male    Female    Total
Income over $50,000         485        385         870
Income below $50,000        65           65        130
Total                                       550        450       1,000

Probability of being male: 550/1000 = 0.55
Probability of earning over $50,000: 870/1000 = 0.87

0.55 x 0.87 = 0.4785

Probability of being male and earning over $50,000: 485/550 = 0.8818

C) No, P(being male | the person earns over $50,000) ≠ P(being male)
