Question

During the next year, the probability that a Company A releases a mobile is 0.7. The probability that mobile is a success, given that it is released by the Company A is 0.8. The probability that a mobile is a success and released by a Company B is 0.28. A mobile released by either Company A or Company B during the next one year is a success. Find the probability that it is released by Company A.

Accepted Answer

C. $P(	ext{Success and released by A}) = 0.7 	imes 0.8 = 0.56$. $P(	ext{Success and released by B}) = 0.28$. Total probability of success = $0.56 + 0.28 = 0.84$. Given that the mobile is a success, the probability it was released by A is $\frac{0.56}{0.84} = \frac{2}{3}$.
