Describe the sample space and event space

Answer 1

The sample space is the space of all possible outcomes. In our case, we can present it in the following form: $S=\{RR,RB,RG,BR,BB,BG,GR,GB,GG\}$ . $S$ is the event space. $R$ denotes a red ball, $B$ denotes a blue ball and $G$ denotes a green ball. The event space is the same.
