A medical researcher is studying the spread of a virus in a population of 1000 laboratory mice. During any week there is an 80 percent probability that an infected mouse will overcome the virus, and during the same week there is a 10 percent probability that a noninfected mouse will become infected. One hundred mice are currently infected with the virus. How many will be infected next week? In 2 weeks?

Contingency Table

A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

Binomial Distribution

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.

Question

A medical researcher is studying the spread of a virus in a
population of 1000 laboratory mice. During any week there is an 80 percent
probability that an infected mouse will overcome the virus, and during the same
week there is a 10 percent probability that a noninfected mouse will become
infected. One hundred mice are currently infected with the virus. How many
will be infected next week? In 2 weeks?

A study tracked a large group of people for 10 years. At the start of the study, 20% were heavy smokers (H), 30% were light smokers (L), and 50% were non-smokers (N). The interest of the study was whether the people in the study died during the study (D) or not die (Dc ). The probability that a light smoker died during the study was twice that of the probability of a non-smoker dying. Also, the probability that light smoker died during the study was half that of the probability of a heavy smoker dying. A randomly selected person from the study died during the study. What is the probability that this person was a heavy smoker (given they died, what is the probability they were a heavy smoker H)?
