Probabilities to solve a specific problem by A, B and C are \(\frac{1}{2}, \frac{1}{3}\) and \(\frac{1}{4}\ respectively. Probability that at least one will solve the problem is:
- A \(\frac{1}{24}\)
- B \(\frac{1}{4}\)
- C \(\frac{23}{24}\)
- D \(\frac{3}{4}\)
Answer & Solution
Correct Answer
(D) \(\frac{3}{4}\)
Step-by-step Solution
Detailed explanation
\( P(\text{A' solves}) = 1 - \frac{1}{2} = \frac{1}{2} \) \( P(\text{B' solves}) = 1 - \frac{1}{3} = \frac{2}{3} \) \( P(\text{C' solves}) = 1 - \frac{1}{4} = \frac{3}{4} \)…
