Complete question:

In the following question,

A bag contains 5 balls all of different colours (one of which is white) three persons A, B, C whose probabilities of speaking truth are 1/2, 2/3 and 3/4 respectively assert that a ball drawn from the bag is white, the probability of the truth of their assertion is

Answer:

The correct answer is 3/5.

Explanation:

• In probability, Bayes' theorem describes the probability of an event, based on prior knowledge of conditions that might be related to the event.
• It is named after Thomas Bayes.
• Solving the question using Bayes theorem,
• $\frac{\frac{1}{5} \times \frac{1}{2} \times \frac{2}{3} \times \frac{3}{4}}{\frac{1}{5} \times \frac{1}{2} \times \frac{2}{3} \times \frac{3}{4} + \frac{4}{5} \times \frac{1}{2} \times \frac{1}{3} \times \frac{1}{4}} = \frac{3}{5<strong>}$
• Hence, the correct answer is 3/5.
