an unfair coin with Pr[H]=0.85 is flipped. If the flip results in head, one student is selected at random from a class of 4 girls and 6 boys. If the flip results in tail, one student is selected from a different class containing 7 girls and 3 boys. Draw a tree and find the probability that: a. a girl is selected b. a boy is selected, given that tails was flipped
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.
