Let \(x\) denote the number of heads in a simultaneous toss of three coins, then \(P(0 < x \leq 3)\)
- A \(\frac{1}{2}\)
- B \(\frac{3}{4}\)
- C \(\frac{7}{8}\)
- D 1
Answer & Solution
Correct Answer
(C) \(\frac{7}{8}\)
Step-by-step Solution
Detailed explanation
\(P(0 \(P(x=0) = \frac{\text{Number of outcomes with 0 heads}}{\text{Total outcomes}} = \frac{1}{2^3} = \frac{1}{8}\) \(P(0 < x \leq 3) = 1 - \frac{1}{8} = \frac{7}{8}\)
