Explanation:
The total number of pens in the box is:
Total number of pens = 11 black pens + 8 blue pens + 6 red pens
Total number of pens = 25 pens
The probability of Roxy selecting a blue pen can be expressed as the ratio of the number of blue pens to the total number of pens:
Probability of selecting a blue pen = Number of blue pens / Total number of pens
Probability of selecting a blue pen = 8 / 25
So, the probability that the pen Roxy selects is blue is 8/25 or approximately 0.32 (rounded to two decimal places).
