Question

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? 1/5 2/5 3/5 4/5

Explanation:

Step1: Identify favorable outcomes

Even numbers: \(2\), \(4\). Unshaded section: \(3\). Total favorable: \(2 + 1=3\) (no overlap as \(3\) is odd).

Step2: Calculate probability

Probability formula: \(P=\frac{\text{Favorable}}{\text{Total}}\). Total sections \(n = 5\). So \(P=\frac{3}{5}\).

Answer:

\(\frac{3}{5}\) (the third option)
