The results of a recent television survey of American TV households revealed that 80 out of every 100 TV households have at least one remote control. What is the probability that a randomly selected TV household does not have at least one remote control?
1 - 80/100 = ?
To find the probability that a randomly selected TV household does not have at least one remote control, we can subtract the probability of having at least one remote control from 1.
Given that 80 out of every 100 TV households have at least one remote control, this implies that 20 out of every 100 TV households do not have at least one remote control.
Thus, the probability that a randomly selected TV household does not have at least one remote control is 20/100 or 0.2.
Therefore, the probability is 0.2 or 20%.
To solve this problem, we need to find the complement of the event "a randomly selected TV household does not have at least one remote control." The complement of an event is the probability of the event not happening.
Given that the survey results showed that 80 out of every 100 TV households have at least one remote control, we can say that 100 - 80 = 20 TV households out of every 100 do not have at least one remote control.
To find the probability, we divide the number of TV households without a remote control by the total number of TV households:
Probability = Number of TV households without a remote control / Total number of TV households.
In this case, the probability is 20 / 100 = 0.2.
So, the probability that a randomly selected TV household does not have at least one remote control is 0.2 or 20%.
