Question

4.4.3 Quiz: Independence

Answer 1

Answer:

$\frac{2}{15}$

Step-by-step explanation:

Lesson : Probability

• 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 : $\frac{1}{3}$

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

$\frac{2}{15}$
