Answer

Answer:

$\frac{24}{38}=\frac{12}{19}$

Explanation:

Step1: Calculate total number of contestants

$6 + 5+5 + 8+10 + 4=38$

Step2: Calculate number of contestants who charmed 5 - 10 or 11 - 20 worms

$(6 + 5)+(5 + 8)=24$

Step3: Calculate probability

Probability = $\frac{24}{38}=\frac{12}{19}$
