Final answer:
The probability that Elena will receive a blue pen is calculated by dividing the number of blue pens by the total number of pens in the box, which is 5 out of 19, or 5/19.
Explanation:
The problem deals with calculating the probability of Elena receiving a blue pen when a pen is drawn at random from a box with different colored pens.
To find the probability, we can use the ratio of the number of blue pens to the total number of pens in the box.
We know that there are 5 blue pens and a total of 4 red pens + 8 purple pens + 2 pink pens + 5 blue pens = 19 pens.
The probability that Elena will receive a blue pen is therefore 5/19, which is the number of blue pens divided by the total number of pens.
