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
