question
a spinner for a board-game is divided into four equal-sized sections colored red, green, yellow, and blue. if you land on a line between the colors, you keep spinning until you land on a color. williams turn is next. which word or phrase describes the probability that he will land on red or blue?
answer
○ impossible
○ unlikely
○ an equal chance or 50-50
○ certain

Explanation:

Step1: Identify total valid outcomes

There are 4 equal-sized colored sections (red, green, yellow, blue), so total valid color outcomes = 4.

Step2: Identify favorable outcomes

Favorable outcomes (red or blue) = 2.

Step3: Calculate probability

Probability = $\frac{\text{Favorable Outcomes}}{\text{Total Outcomes}} = \frac{2}{4} = \frac{1}{2}$

Step4: Match to description

A probability of $\frac{1}{2}$ means an equal 50-50 chance.

Answer:

an equal chance or 50-50
