X = -20p + 500
20p = 500 - x
p = (500 - x)/20
R = xp = x(500 - x)/20 = (500x - x^2)/20

Answer:
90%
Step-by-step explanation:
Probability of households with one TV = 35% or 0.35
Probability of households with two sets = 39% or 0.39
Probability of households with three or more = 16% or 0.16
The probability of a household with no TV set = 0.10 or 10% (1 - 0.35 - 0.39 - 0.16)
Therefore, the probability of a household with at least one or more sets = 90% (35% + 39% + 16%) or 100% - 10%.
Probability is the chance that something may occur out of many events. To calculate probability, we divide the number of events by the number of possible outcomes.
