A lender will make an 80% loan-to-value loan on a property that is appraised for $72,250 and sells for $73,500. If the buyer has

anyanavicka [17]

Answer:

$1,250

Step-by-step explanation:

We are given;

Loan to value ratio;LTV = 80% = 0.8

Appraised value of property = $72,250

Selling value of property = $73,500

Now, the formula for Loan to value ratio is;

LTV = Loan amount/Appraised value of property

0.8 = loan amount/72250

Cross multiply to get;

Loan amount = 0.8 × 72250 = $57,800

Now,we are told that he has saved $14,450.

Thus, total money raised including loan = $57,800 + $14,450 = $72,250

Since the selling value = $73,500, then,

Amount left for him to save in order to make down payment = $73,500 - $72,250 = $1,250

Help binomial distributions

Ymorist [56]

We have the formula to compute the probability of having exactly k successed over n trials, given a probability p of success (and implicitly a probability 1-p of failure), which is

$P(\text{k successed on n trials}) = \binom{n}{k}p^k(1-p)^{n-k}$

Now, the probability of at least 3 successes is the union of the following event: exactly three successes,exactly four successes and exactly five successes.

We can compute their probability and sum them: $\binom{5}{3}\left(\frac{3}{7}\right)^3\left(\frac{4}{7}\right)^2 + \binom{5}{4}\left(\frac{3}{7}\right)^4\left(\frac{4}{7}\right)^1 + \binom{5}{5}\left(\frac{3}{7}\right)^5 \approx 0.36788$

So, the answer is about 36.79%
