Answer: a) 0.1216

b) 0.8784

Step-by-step explanation:

 Let P(watch) = 0.19 ;

And p(don't watch) = 0.81

Find the probability that none of the households are tuned to Found. 

P(none) = (0.81)^10 = 0.1216

Find the probability that at least one household is tuned to Found. 

P(at least one) = 1-P(none)

1 - 0.1216 = 0.8784
