Answer
$\frac{1}{2}$
Work Step by Step
To find a probability $P(x)$, we want to divide the number of events in the group $x$, and divide that number by the total number of events. In this case, there are $3$ odd numbers on the spinner, and $6$ numbers in total, so P(odd) is $\frac{3}{6}$, which is equivalent to $\frac{1}{2}$.
