First we need to choose from "Posivite Test" column:
\frac{12}{12+78} =  \frac{12}{90} = 0,1333(3)

The <em>correct answer</em> is:

0.13

Explanation:

Using the two-way table, we focus on the column labeled "Positive Test." There are 78+12 = 90 people who had a positive test. Out of these, 12 were not pregnant. This is a probability of 12/90 = 0.133333 = 0.13.

butalik [34]
Total applications = 75
Apartments on north side of town = 4
Apartments on South side of town = 5

First  person has a 4/75 chance of getting a house in the north side
P(A) = 4/75

And second person has a 3/74 chance of getting a house in the north side
P(B) = 3/74

Probability that 2 qualified applicants will be selected for the north side of town =  P(A∩B) = P(A) x P(B) = (4 ÷ 75) x (3 ÷ 74) = 0.05333 x 0.04054 = 0.00216 

First  person has a 5/75 chance of getting a house in the south side 
P(A) = 5/75

And second person has a 4/74 chance of getting a house in the south side
P(B) = 4/74

Probability that 2 qualified applicants will be selected for the south side of town =  P(A∩B) = P(A) x P(B) = (5 ÷ 75) x (4 ÷ 74) = 0.06666 x 0.05405 = 0.00360
