  1. There are 1000 households in a town. Specifically, there are 100 households with 1 member, 200 households with 2 members, 300 households with 3 members, 200 households with 4 members, 100 households with 5 members, and 100 households with 6 members. We pick a household at random and let X = the number of people in the chosen household.
    1. What is F(3)
    2. For what values of x is F(x) = 0.8?

1.) Although 24% of all Martians have three eyes, only 6% of the members of the Martian Senate are three-eyed. Which of the following conclusions may be validly drawn from this discrepancy? This is clear evidence of eyeism. Differences in outcome such as this one prove definitively that Martian society is overrun with eyeists. While this doesn’t necessarily prove that Mars is overrun by eyeists, it does show that systemic eyeism must be a big problem on the red planet....
