A fair coin is tossed three times. What is the probability that you get Tails EXACTLY two out of the three times? Better draw up the tree diagram for this situation. At every decision point (branching point), the coin will come up heads (H) or Tails (T) with a probability of 1/2 for each.
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.

Better draw up the tree diagram for this situation. At every decision point (branching point), the coin will come up heads (H) or Tails (T) with a probability of 1/2 for each.
In the below tree diagram the first level of branches represent the possible results of first toss. The second and third level of branches represent the possible results of 2nd and 3rd toss of the coin.
