Explanation / Answer

a)

NE = 150

Total in ober 500,000 = 150+25+40+60 = 275

Prob = 150 / 275 = 0.5454

b)

Under 50000 = 35

Total = 35 +25+ 90

prob = 35/150 = 0.233

c)

SW = 15+70+40 = 125

500000 or less = 70+15 = 85

Prob = 85/125 = 0.68

d)

total for 500000 or less =

30+60+35+90+35+70+5+30 = 355

SW = 15+70 = 85

prob is

85/355 = 0.2394
