Chapter 7 - Section 7.7 - Basics of Probability - 7.7 Exercises - Page 689: 5


The sample space is $S=\left\{(3,3), (3,2), (3,1), (2,3), (2,2), (2,1), (1,3), (1,2), (1,1)\right\}$

Work Step by Step

The sample space is a set that consists of all the possible results of the experiment. Here, at the first spin, all can be pointed at. At the second draw, also all three numbers can be pointed at. Therefore there will be $3\times3=9$ possible outcomes. The sample space is $S=\left\{(3,3), (3,2), (3,1), (2,3), (2,2), (2,1), (1,3), (1,2), (1,1)\right\}$ (the first number represents the first spin, the second number represents the second spin.)
