Question

A spinner is divided into 13 equal-sized sections, and each section is labeled with a number 1 through 13.If Kathryn spins the arrow on the spinner, what is the probability that the arrow will land on a section with an even number or a number less than 5?OA.813110B.Oc.OD.

Answer 1

Answer:

The probability that the arrow will land on a section with an even number or a number less than 5 is:

$\frac{8}{13}$

Explanation:

Given that A spinner is divided into 13 equal-sized sections, and each section is labeled with a number 1 through 13.

the probability that the arrow will land on a section with an even number or a number less than 5 will be;

$\begin{gathered} P=\frac{nu\text{mber of even number or numbers less than 5}}{\text{total numbers}} \\ P=\frac{n(e)}{n(t)} \end{gathered}$

Numbers with an even number or a number less than 5 will be;

$\begin{gathered} (1,2,3,4,6,8,10,12) \\ n(e)=8 \\ n(t)=13 \end{gathered}$

Substituting the values;

$P=\frac{8}{13}$

The probability that the arrow will land on a section with an even number or a number less than 5 is:

$\frac{8}{13}$
