Build two-step sample spaces with and without replacement
Two fair spinners are spun independently. The first has equal sectors numbered 1 to 4. The second has equal sectors numbered 1 to 2
Record each pair as first,second. The ? marks one missing outcome
| First ↓ | 1 | 2 |
|---|---|---|
| 1 | 1,1 | 1,2 |
| 2 | ? | 2,2 |
| 3 | 3,1 | 3,2 |
| 4 | 4,1 | 4,2 |
Event \(E\): at least one number is 1
