Answer:
0.1749
Step-by-step explanation:
We are to find the probability that none of the house-holds tuned to 50 minutes.
P(tune to 50 minutes) = 0.16
p = 0.16
q = 1 - 0.16
q = 0.84
number of households (n) = 10
x = number of households that tuned at 50 minutes
since none of the household tuned, then:
x = 0
Using the binomial expression:
P(x =0) = 0.1749
