Answer:
[tex]\frac{2}{15}[/tex]
Step-by-step explanation:
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]
