Sample space={1,2,3,4,5,6,7,8,9,10} = 10 total outcomes

a) Favorable odds number = {1,3,5,7,9} = 5 favorable outcomes
b) Favorable > 6 = {7,8,9,10} = 4 favorable outcomes

P(drawing ODD) = 5/10 = 1/2
P(drawing >6) = 4/10 = 2/5

P(drawing odd AND > 6) = P( odd ∩ > 6) = (1/2).(2/5) = 2/10 = 1/5

And P( odd ∩ > 6) = 0.2

Answer:

c. 8 months.

Step-by-step explanation:

First off let's get the current total of how much we have saved.

2/3 of $23,000 = 15,333.33.

Now we need to get our total salary to calculate for our Social Security and Medicare.

Total Salary : $1312.00 x 2 = $2,624.00

Social Security : 6.2% or 0.062 x 2,624 = $162.69

Medicare : 1.45 or 0.0145 x 2,624 = $38.05

Now that we have our Social Security and Medicare, we can then solve for our taxes.

Taxes: $53 + $101.35 = 154.35 x 2 = $308.7

Now we can add our monthly expenses to the other expenses.

Monthly Expenses : $1,150.12

1,150.12 + 162.69 + 38.05 + 308.7

= $1659.56 Total Expenses.

Now that we have our total expenses we simply subtract it to our monthly salary.

2624.00-1659.56

= $964.44 Extra Money Monthly

Now we proceed to solve for how much more we need to make the total payment.

23000 - 15,333.33

= 7666.67

Now that we have out total balance, we just need to divide the balance to our extra money monthly.

7666.67 / 964.44

= 7.949 Months or 8 Months
