Question

algebra i b-cr
the spinner is equally likely to land on any of the five sections.
what is the probability that the spinner lands on an even number or on the unshaded section?
○ $\frac{1}{5}$
○ $\frac{2}{5}$
○ $\frac{3}{5}$
○ $\frac{4}{5}$
mark this and return

Explanation:

Step1: Identify target sections

First, list even numbers and unshaded section: Even numbers are 2,4; unshaded section is 3. Total unique target sections: 2,3,4.

Step2: Count total & favorable outcomes

Total sections: $n(\text{total})=5$. Favorable sections: $n(\text{favorable})=3$.

Step3: Calculate probability

Probability = $\frac{\text{Favorable Outcomes}}{\text{Total Outcomes}}$
$\text{Probability} = \frac{3}{5}$

Answer:

$\frac{3}{5}$ (Option: $\boldsymbol{\frac{3}{5}}$)
