Question
A question is given to Saket, Ankush and Prem.
Probability that Saket, Ankush and Prem can solve the question is 1/3, 2/5 and 1/2. Find the probability that the question will be solved.Solution
Probability that no one can solve the given question, => (1 - 1/3) × (1 - 2/5) × (1- 1/2) => 2/3 × 3/5 × 1/2 => 1/5 Probability that the question will be solved = 1 – Probability that no one can solve the question = 1 – 1/5 = 4/5
