Coin Cube Outcomes
1. **Stating the problem:**
We have a coin flip (2 outcomes: heads or tails) and a roll of a number cube (6 outcomes: numbers 1 through 6). We want to find:
(a) Total number of outcomes.
(b) Number of outcomes that do not involve rolling a 2.
(c) Number of outcomes that involve heads and an odd number.
2. **Formula and rules:**
The total number of outcomes when two independent events occur is the product of the number of outcomes for each event.
3. **Calculations:**
(a) Total outcomes = number of coin outcomes × number of cube outcomes = $2 \times 6 = 12$
(b) Outcomes not involving rolling a 2 means the cube shows any number except 2, so 5 possible numbers (1,3,4,5,6). For each coin outcome, there are 5 such cube outcomes.
Number of outcomes not involving 2 = $2 \times 5 = 10$
(c) Outcomes involving heads and an odd number. Odd numbers on the cube are 1, 3, 5 (3 numbers).
Number of such outcomes = $1 \times 3 = 3$
4. **Summary:**
- Total outcomes: 12
- Outcomes without rolling 2: 10
- Outcomes with heads and odd number: 3
This completes the problem.
