Missing part of the question
Some parts of California are particularly earthquake-prone. Suppose that in one metropolitan area, 25% of all homeowners.....................
Answer:
Step-by-step explanation:
Given
Solving (a): The probability distribution of x
We have:
The probability of not having earthquake insurance (q) is:
If x has insurance, then n - x do not.
The distribution follows a binomial pattern. So, the probability distribution is:
Substitute 4 for n
Solving (b): The most likely value of x i.e. The mean
We have:
and
Solving (c): At least 2 of 4 selected have earthquake insurance.
This is calculated as
So:
--- approximated
The answer is between 45,000,000-65,000,000
Answer:
P (She selects the route of four specific capitals) = 
D. No,it is not practical to list all of the different possible routes because the number of possible permutations is very large.
Step-by-step explanation:
Let's start assuming that each route is equally likely to be chosen.
Assuming this, we can calculate P(A) where the event A is ''She selects the route of four specific capitals'' doing the following :
P(A) = Favourable cases in which the route of four specific capitals is selected / Total number of ways in 4 of 42 states
The favourable cases in which the route of four specific capitals is selected is equal to 1 .
For the denominator we need the permutation number of 4 in 42.
The permutation number is defined as :
The probability of event A is :
Finally for the other question : The option D is the correct because the number of possible permutations is 2686320 and is very large to be listed.
