Answer:
19% of households have more cars than the garage can hold
Step-by-step explanation:
We are given the following distribution for the number of cars owned by a family.
Number of cars X: 0 1 2 3 4 5 6
Probability: 0.07 0.31 0.43 0.12 0.04 0.02 0.01
We have to find the percentage of households have more cars than the garage can hold.
A garage can hold two cars. Thus, the household with more than two cars are the households that have more cars than the garage can hold.
The given distribution is a discrete probability distribution.
Thus, we evaluate:
Thus, 19% of households have more cars than the garage can hold.
n = 15
the nth term of an arithmetic sequence is = a₁ + (n-1)d
where d is the common difference
d = a₂ - a₁ = 6 - 2 = 4
= 2 + 4n - 4 = 58
4n - 2 = 58
4n = 60 ( divide both sides by 4 )
n = 15
