Answer: [tex]\dfrac{2}{5}[/tex]
Step-by-step explanation:
Given
A desk drawer has 8 blue, 7 black, and 10 green pens
The favorable chances of drawing a green pen are 10
Probability is given by the ratio of favorable outcomes to the total outcomes.
So, the probability of drawing a green pen is
[tex]\Rightarrow P=\dfrac{10}{8+7+10}\\\\\Rightarrow P=\dfrac{10}{25}\\\\\Rightarrow P=\dfrac{2}{5}[/tex]
