Answer: OPTION C.

Step-by-step explanation:

The formula of Exponential Growth has the following form:

$y=C(1+r)^t$

Where "C" is the initial value, "r" is the growth rate and "t" is the time in years.

In this case we have the following expression:

$1,500(1.02)^t$

We can identify that:

$C=1,500\\\\r=0.02=2\%\\$

Therefore, the meaning of the expression is: The initial number of trees planted by the agency is 1,500, and the growth rate is 2% per year.

On a multiple choice test, if you randomly guessed on three questions, then what is the probability you got at least one of them

snow_lady [41]

Answer:

Number of Questions =3

Probability of giving a correct answer

$=\frac{1}{3}$

Probability of giving two correct answers

$=\frac{2}{3}$

Probability of giving all correct answers

$=\frac{3}{3}\\\\=1$

Probability that at least one of them is correct

$=_{1}^{3}\textrm{C}\\\\=\frac{3!}{(3-1)! \times1!}\\\\=3 \text{ways}\\\\=\frac{1}{3} \times \frac{1}{3} \times \frac{1}{3} \\\\=\frac{1}{27}$

Probability that two of them is correct

$=_{2}^{3}\textrm{C}\\\\=\frac{3!}{(3-2)! \times2!}\\\\=3 \text{ways}\\\\=\frac{2}{3} \times \frac{2}{3} \times \frac{2}{3} \\\\=\frac{8}{27}$

Probability that all of them is correct

$=_{3}^{3}\textrm{C}\\\\=\frac{3!}{(3-3)! \times3!}\\\\=1 \text{way}\\\\=1$

So, Required probability

$=\frac{1}{27} \times \frac{8}{27} \times 1\\\\=\frac{8}{729}$
