The total human population of the planet Earth is something in the vicinity of 7 billion. If you choose one human being at random from across the entire planet, each individual on the planet is equally likely to be chosen. Corresponding probabilites are impractically small. Use this information to answer the following questions This human population of the entire planet Earth can be divided roughly into thirds: About 1/3 of the population is adult (ages 18 -65) men; about 1/3 is adult women; and about 1/3 is non-adults (children and older adults of either gender). Fractions (or proportions or percents) of the population can also be probabilities. If you choose one human being at random from the entire planet Earth, individual probabilities are (still) vanishingly small, but the fraction in any given group can be used as the probability of choosing someone from that group.
If you pick one human being from the population of the planet Earth, what is the probability that you get an adult of either gender?
FRACTION answer.
Homework Answers
Pr(Adult of either gender) = P ( adult men ) + P( adult women ) = 1/3 + 1/3 = 2/3
So required probability is 2/3 .

Q1 According to United Nations, human population reached 7 billion on October 31, 2011. Using this benchmark and an estimated increase of 3 new persons added to the human population every second (i.e., births – deaths = net increase of 3 p/s), calculate the following: a. On what date (day, month, year) in the future will we reach 8 billion? b. What the population was on the day you were born? c. How long it took for our population to...

8. A satellite is in circular orbit about planet Rosseforp at an altitude (above the surface) h. When h = 1.75 × 104 km, the period of the orbit is T = 12 hours. If Rosseforp has a mass of 7.0 × 1024 kg, what does the satellite weigh on the surface of Rosseforp if it weighs 850 N on the surface of Earth? You are part of an expedition to planet Rosseforp (same planet as in the previous question)....

Assume total cholesterol levels (TChol) are normally distributed with mean μ = 215 mg/dl and standard deviation σ = 30 mg/dl for the adult American population. That is, TChol ~ N(215, 302). Total cholesterol values of 240 mg/dl or greater are considered high; and levels in the range of 200 to 240 are called borderline high. a. What proportion of this population do we expect to find with high cholesterol? What proportion do we expect to find with borderline high...

Question 16 (5 points) Saved Opinion polls find that 20% of Americans adults claim that they don't get enough sleep. Suppose you take a random sample of 20 American adults and count the number of individuals in your sample who claim that they never have time to relax. Based on this information, match the following probabilities. 1. What is the probability that at least 8 out of 20 American adults don't get enough sleep? 0.968 0.055 2. What is the...
