Drop a thumbtack and observe how it lands: pt1: Desribe how you could usea relative frequency to estiate the probability that a tumbtack will land with its flat side down: a. count the number of times it lands point down and divide by the total number of times dropped b. count the number of times it lands flat side down and divide by the total number of times it dropped c. count the number of times it lands flat side down, subtract the number of time it lans point down, and divide by the total number of times dropped pt 2: What is the sample space of outcomes for the thumbtack? choose all that apply: - up - down - left - right pt 3: how would you make a probability assignment to this sample space if when you drop 500 tacks, 345 land flat side down? p (up)= p(down)=
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.
Drop a thumbtack and observe how it lands:
pt1: Desribe how you could usea relative frequency to estiate the
a. count the number of times it lands point down and divide by the total number of times dropped
b. count the number of times it lands flat side down and divide by the total number of times it dropped
c. count the number of times it lands flat side down, subtract the number of time it lans point down, and divide by the total number of times dropped
pt 2: What is the
- up
- down
- left
- right
pt 3: how would you make a probability assignment to this sample space if when you drop 500 tacks, 345 land flat side down?
p (up)=
p(down)=
