2 Probability You already know much about probability. For example. suppose there is a sixsided die. where each face is labeled 1 through 6. You'd probably tell me the odds that a 1 is rolled is 1/6. \""113"? Behind this understanding are the following ideas. The sample space. S. is a 1. 2. 3. 4. 5. or a 6. which we can denote as {1. 2. 3. 4. 5. 5}. And we are interested in the outcome of landing on each face. (Alternatively. we could be interested in the outcome that the die lands on an even or oddnumbered face.)
