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 : $\frac{1}{3}$

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

$\frac{2}{15}$

Answer:

Step-by-step explanation:

This is the fraction we use to solve this problem $\frac{Ounces}{Flour}$

Fractions are $\frac{8}{3}$ and $\frac{96}{x}$

We now ask ourselves

$8 * x = 96\\x = 12$

Since whatever we do to the numerator we have to to the same to the denominator, we multiply 3 and 12

$3 * 12 = x\\x = 36$

Hope this helps!
