Rent Own
20-39 300 140 440
40-59 125 428 553
60+ 220 287 507
645 955 1500
P(20-39) = 440/1500
P(rent given 40-59) = 125/553
P(60+ and own) = 287/1500
P(40-59 and rent) = 125/1500
P(20-39 given rent) = 300/645
***SUMMARY of probability rules: pg. 154, problems pg. 155-162
E = event; n = possible outcome
Total number of outcomes of Em is n1*n2*n3.....*nm
Ex: I have to take 3 math, 2 language, 2 history
