Answer
$\frac{1}{3}$
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 $2$ numbers that are more than $4$ on the spinner (5 and 6 are both greater than 4), and $6$ numbers in total, so P(>4) is $\frac{2}{6}$, which is equivalent to $\frac{1}{3}$.
