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.

Answer:
1/3
Step-by-step explanation:
Of the 15 students in the class, 5 are boys with glasses. The probability of selecting one at random is 5/15 = 1/3.
Answer:
- Francesca: 2879 1/6 miles
- Sophia: 575 5/6 miles
Step-by-step explanation:
For each mile that Sophia ran, Francesca ran 5 miles. Then Sophia ran 1/6 of their total. Sophia ran ...
(1/6)(3455) = 575 5/6 miles
Francesca ran the remaining miles:
3455 -575 5/6 = 2879 1/6 miles
