Final answer:
The number of pencils that are red and green is 54.
Step-by-step explanation:
The total number of pencils Sylvania has is 95. Out of these, 33 are red or blue.
The number of pencils that are red is 41, and the number of pencils that are green is 21.
To find the number of pencils that are red and green, we can subtract the number of red pencils from the total number of pencils.
Therefore, the number of pencils that are red and green is 95 - 41 = 54.
