To find the experimental probability of drawing a blue highlighter, we need to count the number of times a blue highlighter was drawn and divide it by the total number of draws.
From the table, we can see that a blue highlighter was drawn 3 times out of 20 draws.
Experimental probability of drawing a blue highlighter = Number of times blue highlighter was drawn / Total number of draws
Experimental probability of drawing a blue highlighter = 3/20
Experimental probability of drawing a blue highlighter = 0.15 or 15%
Therefore, the experimental probability of drawing a blue highlighter is 15%.
