Question16. Which of the following is a composite number? a. 11 b. 10 c. 13 d. 23

Studdy Solution
The **answer** is b. $\text{10}$ is the only composite number in the list, since it's divisible by $\text{2}$ and $\text{5}$, in addition to $\text{1}$ and $\text{10}$.
The other options, $\text{11}$, $\text{13}$, and $\text{23}$, are all prime numbers!
