Question

What are the odds in favor of spinning red?

• A. $1:5$
• B. $1:4$
• C. $4:1$
• D. $5:1$

Answer 1

The correct option is B $1:4$


As per the given spinner,

Number of favorable outcomes
$=$ Number of red colored region
$=1$

Number of unfavorable outcomes
$=$ Number of non-red colored regions
$=4$

Now, $\text{Odds in favor of spinning red}=\frac{\text{Number of favorable outcome}}{\text{Number of unfavorable outcome}}$

$\Rightarrow \text{Odds in favor of spinning red}=\frac{1}{4}=1:4$

Therefore, option (b.) is the correct choice.
