Coin Tossing. A balanced dime is tossed HHH HTH THH TTH HHT HTT THT TTT Here, for example, HHT means that the first two tosses come up heads and the third tails. Find the probability that a. exactly two of the three tosses come up heads.b. the last two tosses come up tails.c. all three tosses come up the same.d. the second toss comes up heads.
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.
