Answer
$0$
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 $0$ numbers that are $7$ on the spinner, and $6$ numbers in total, so P(7) is $\frac{0}{6}$, which is equivalent to $0$.
