Answer

a) 0.99 b)0.9801. c) Series connection.

Work Step by Step

a) The tv doesn't get damaged if the second one stays good, which has the probability of 0.99. b) The tv doesn't get damaged if both of them stay good, because if one of them gets wrong then it affects the tv. Hence the probability of both staying good is:$0.99\cdot0.99=0.9801$. b)0.99>0.9801, so we should choose the series connection.
