Parveen flips a coin and then spins the arrow on the spinner.What is the total number of outcomes for this event?
Correct answer: B. 10
- A. 7
- B. 10
- C. 15
- D. 25
Explanation
To calculate the total number of outcomes, consider both the coin and the spinner. A coin flip results in 2 possible outcomes: heads or tails. Assuming the spinner has 5 equal sections, it results in 5 possible outcomes. Therefore, the total number of outcomes when combining the coin flip and the spinner spin is 2 (coin outcomes) × 5 (spinner outcomes) = 10. Thus, the correct answer is Option B: 10. Other options arise from incorrect assumptions about the number of sections on the spinner or errors in multiplying the outcomes.
