The variance of the binomial distribution of the number of households with landline service is 2.
<h3>What is the binomial probability distribution?</h3>
It is the probability of <u>exactly x successes on n repeated trials, with p probability</u> of a success on each trial.
The variance of the distribution is given by:
V(X) = np(1 - p)
In this problem, the parameters are given as follows:
n = 8, p = 0.504.
Hence the variance is given by:
V(X) = 8 x 0.504 x 0.496 = 2.

Hey there
Lets solve this question together,
Convert <span>76.8%</span><span> to a decimal.
</span>
Multiply 0.768<span> by </span>x<span> to get </span><span>0.768x</span><span>.
</span>
Multiply<span> each </span>term<span> by </span><span>1 / 0.768</span><span> and simplify.
