Unformatted text preview: Math331, Spring 2008 Instructor: David Anderson Section 1.1 and 1.2 Hw answers Homework: pgs. 9  11, #s 2, 3, 5, 9, 13, 17(a) 2. The sample space is given by S = { ( i, j, k )  i, j, k { red,blue }} . 3. The sample space is S = { t : t (0 , 20) } . The event that the number is an integer is E = { 1 , 2 , 3 , . . . , 19 } . 5. E is the event that the sum is odd. F is the event that at least one 1 is rolled. E F implies one 1 and one even number (so the sum is odd). E c F implies one 1 and one odd number (so the sum is even). E c F c implies the sum is even and neither was a 1. Thus, both even or both in { 3 , 5 } . 9. Let a i b j be the event that passenger a gets off at hotel i and likewise for b . Here i, j { 1 , 2 , 3 } . Then S = { a i b j : i, j { 1 , 2 , 3 }} . Alternatively (there is no unique answer here) S = { ( i, j ) : i, j { 1 , 2 , 3 }} , where the first element of ( , ) represents the number of the hotel (1,2, or 3) that passenger...
