Answer:
238
Step-by-step explanation:
Start with Raven's ants since hers is the one that everyone else's is based off of.
Raven = 208
Haley has half of that plus 76, so
Haley = (208/2) + 76
Haley = 180
If Haley's farm doubles in population, she would have 360 ants. That number is equal to Nate's number + 122. We have an equation of sorts there to solve for Nate's ants:
180(2) = N + 122 so
360 = N + 122 and
N = 238
Nate has 238 ants in his farm.

4 1/2 is the exact answer. 5 is the estimate.
Answer:
a. Binomial random variable (n=4, p=0.25)
b. Attached.
c. X=1
Step-by-step explanation:
This can be modeled as a binomial random variable, with parameters n=4 (size of the sample) and p=0.25 (proportion of homeowners that are insured against earthquake damage).
a. The probability that X=k homeowners, from the sample of 4, have eartquake insurance is:

The sample space for X is {0,1,2,3,4}
The associated probabilties are:

b. The histogram is attached.
c. The most likely value for X is the expected value for X (E(X)).
Is calculated as:
