Experiment: Toss a fair coin 3 times. Let A be the event of tossing at most 1 heads in your 3 tosses. Give the following probability as a fraction in lowest terms P(A) =
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.
Given: A fair coin is tossed 3 times.
A is the event of tossing at most 1 head in your 3 tosses.
Both Heads and Tails are equally likely in an experiment, therefore the probability of both Heads(H) and Tails(T) will be each .
The possible sample space from 3 tosses is: {HHH, HHT, HTH, THH, HTT, THT, TTH, TTT}
