Answer

Explanation:

Step1: Calculate total number of contestants

Add up all the values in the table. $3 + 5+2 + 3=13$.

Step2: Determine number of favorable - cases

The number of contestants who charmed 5 - 10 worms and tried tapping the ground is 3.

Step3: Calculate probability

The probability $P$ is the number of favorable cases divided by the total number of cases. So $P=\frac{3}{13}$.

Answer:

$\frac{3}{13}$
