Answer:
Part A:
Rent = $7380
Mortgage payments = $9800
Insurance = $145
Taxes, insurance, maintenance = 
= $2830
Loss of Interest on security deposit = (650*6%) = $39
Interest lost on down payment and closing cost = (4,500*6%) = $270
Growth in equity = $225
Annual appreciation = $1700
Tax savings for mortgage interest = (9,575*28%) = $2,681
Tax savings for property taxes = (1,780*28%) = $498
Total rental cost = 
dollars
Total buying costs = 
dollars
Part B:
You should consider rent because the cost of renting is less than the cost of buying.
I would say for every 1 brownie, there are 5 cookies.
Answer:
0.9375 = 93.75% probability that at least one of the four children is a girl.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
We have the following sample space
In which b means boy, g means girl
b - b - b - b
b - b - b - g
b - b - g - b
b - b - g - g
b - g - b - b
b - g - b - g
b - g - g - b
b - g - g - g
g - b - b - b
g - b - b - g
g - b - g - b
g - b - g - g
g - g - b - b
g - g - b - g
g - g - g - b
g - g - g - g
Total outcomes
There are 16 total outcomes(size of the sample space)
Desired outcomes
Of these outcomes, only 1(b - b - b - b) there is not a girl.
So the number of desired outcomes is 15.
Probability:
0.9375 = 93.75% probability that at least one of the four children is a girl.
