34. The battery in a new popular personal electronics device is suspected of failing and catching on fire. There are at total of 500 of these devices currently in use. Tests indicate that approximately 1 in 100 of these batteries will fail within one year. If fewer than 4 of the batteries in use are reported as failed within one year than NO recall will be performed. Using a poisson approximation, what is the approximate probability of having to perform a recall. a. 0.440 b. 0.560 с. 0.735 d. None of the above
