Given:
• Number of blue pens = 14
,
• Number of black pens = 8
,
• Number of red pens = 6
Let's find the probability that the students will pick NOT a blue or a black pen.
To find the probability, we have the formula:
P(NOT a blue or black) = 1 - (P(blue) + P(black)
Where:

Where:
total number of pens = 14 + 8 + 6 = 28
Thus, we have:

Solving further:

Therefore, the probability is 3/14
