So for part d, where we're asked for the percentage, oops, let me fix that there, the percentage of households in the survey with three televisions, the way that we calculate this is we would take the number in the survey with three televisions, so the number of times that three occurs in the dataset, then we divide that by the number of households in the survey.
00:35
We can think of this as being equal to the probability of randomly selecting a household that has three televisions from the survey, or we could think of this as the relative frequency of a household having three televisions in the survey.

So, one moment here.
01:04
So looking at the data that we have, we have one, two, three, four, five, five, 6, and 7.
01:20
So we have that the frequency that x is, or the frequency of x equals 3 is equal to 7, or we can say that that's the number of times that 3 occurs is equal to 7...
