Answer
$0.23$, $0$, $\frac{3}{4}$
Work Step by Step
According to the Rules of Probabilities, if $P(E)$ is the probability of an event $E$:
$0\leq P(E)\leq1$
$0\leq0.23\leq1$. So, $0.23$ can be the probability of an event.
$0\leq0\leq1$. So, $0$ can be the probability of an event.
$\frac{3}{2}\gt1$. So, $\frac{3}{2}$ can not be the probability of an event.
$0\leq\frac{3}{4}\leq1$. So, $\frac{3}{4}$ can be the probability of an event.
$-1.32\lt0$. So, $-1.32$ can not be the probability of an event.
