The percentage of the yellow gumdrops is 21.621...%
Explanation
Orange gumdrops = 17 , Yellow gumdrops = 8 and Black gumdrops = 12
So, the total gumdrops = 17 + 8 + 12 = 37
Percentage of yellow gumdrops = [(Yellow gumdrops) / (Total gumdrops)] × 100%
So, the percentage [tex]= \frac{8}{37}* 100 = \frac{800}{37}= 21.621...[/tex]%
