Answer:

$\frac{2}{15}$

Step-by-step explanation:

<h2><u>Lesson : Probability</u></h2><h2><u></u></h2>

We have a bag with 4 white chips and 6 black chips
Question : What is the probability of randomly choosing a white chip, not replacing it, and then randomly choosing another white chip?

4 white and 6 black

4 + 6 = 10

Choosing the first white chip : $\frac{2}{5}$

Since we took one out , now

3 white chips , 6 black chips

3 + 6 = 9

Choosing another white chip : $\frac{1}{3}$

$\frac{2}{5} * \frac{1}{3}$

$\frac{2}{15}$

Natural logarithms ln and Euler's number e
Logarithmic Property [Multiplying]: $\displaystyle log(ab) = log(a) + log(b)$
Logarithmic Property [Dividing]: $\displaystyle log(\frac{a}{b}) = log(a) - log(b)$ <u> </u>

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

<em /> $\displaystyle ln(\frac{2e}{x})$ <em />

<em />

<u>Step 2: Simplify</u>

Expand [Logarithmic Property - Dividing]: $\displaystyle ln(\frac{2e}{x}) = ln(2e) - ln(x)$
Expand [Logarithmic Property - Multiplying]: $\displaystyle ln(\frac{2e}{x}) = ln(2) + ln(e) - ln(x)$
Simplify: $\displaystyle ln(\frac{2e}{x}) = ln(2) + 1 - ln(x)$
Rewrite: $\displaystyle ln(\frac{2e}{x}) = 1 + ln(2) - ln(x)$
