Answer:

[tex]\frac{2}{15}[/tex]

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 : [tex]\frac{2}{5}[/tex]

Since we took one out , now

3 white chips , 6 black chips

3 + 6 = 9

Choosing another white chip : [tex]\frac{1}{3}[/tex]

[tex]\frac{2}{5} * \frac{1}{3}[/tex]

[tex]\frac{2}{15}[/tex]
