There is currently a global pandemic and many researchers and scientists are working assiduously to find a vaccine. Assume that Advanced Researcher, a company that is currently testing a few vaccines confirms an 80% chance of effectiveness of one of their vaccines. a. Which probability distribution would you use to calculate the probability of success or failure of Advanced Researcher's vaccine if it were to be administered to people in society? b. What are the assumptions of the probability distribution identified in part "a."? c. Assume that the vaccine is given to a group of 50 people from Jamaica, what is the probability that it is an effective in exactly 40 persons? Interpretation your result.

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.

a. Which probability distribution would you use to calculate the probability of success or failure
of Advanced Researcher's vaccine if it were to be administered to people in society?
b. What are the assumptions of the probability distribution identified in part "a."?
c. Assume that the vaccine is given to a group of 50 people from Jamaica, what is the
probability that it is an effective in exactly 40 persons? Interpretation your result.
Question two
Assume that the time that will be taken to complete this assignment is a random variable with a
normal distribution. Also, assume that the average time to complete this assignment is 8 hours
and that the standard deviation is 1 hour. What is the probability that a student will finish this
assignment in a time period less than 4 hours? Interpret your result.
