Answer:  The required probability is 0.10.

Step-by-step explanation:  Given that Marla is looking for a new car. She has test-driven two cars A and B but can only purchase one.

We are to find the probability  that she will not purchase either car A or car B.

Let, 'C' denotes the event that Marla will purchase car A and 'D' denotes the event that Marla will purchase car 'B'.

Then, according to the given information, we have

P(A)=0.52,~~~P(B)=0.38.

Since Marla cannot purchase both the cars, so the events A and B are disjoint.

That is,

A\cap B=\phi~~~~~\Rightarrow P(A\cap B)=0.

Therefore, the probability that Marla will purchase either car A or car B is given by

P(A\cup B)=P(A)+P(B)-P(A\cap B)=0.52+0.38-0=0.90.

Hence, the probability that she will not purchase either car A or car B will be

P^\prime(A\cup B)=1-P(A\cup B)=0-0.90=0.10.

Thus, the required probability is 0.10.

The probability that she won't buy either car is .10. You add the two probabilities that were previously stated and then subtract them from 1.00. 

.52 + .38 = .90

1.00 - .90 = .10

Monica [59]

Answer:

The student will have to reimburse 2,991.03 two years later.

Step-by-step explanation:

This is a compound interest problem:

The compound interest formula is given by:

A = P(1 + \frac{r}{n})^{nt}

In which A is the amount of money, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per unit t and t is the time the money is invested or borrowed for.

In this problem, we have that:

A is the amount the student will have to reimburse two years later.

P is his loan. so P = 2,500

The bank loans this money at a rate of 9 % capitalized monthly. This means that r = 0.09 and n = 12, since the money is compounded monthly, this means, 12 times in a year.

He will have to reimburse two years later, so t = 2

A = P(1 + \frac{r}{n})^{nt}

A = 2,500(1 + \frac{0.09}{12})^{24}

A = 2,991.03

The student will have to reimburse 2,991.03 two years later.
