During a recent bridge game, once the lead card had been played and the dummy’s hand revealed, the declarer took a moment to count up the number of cards in each suit with the results given below: Suit We They Spades 6 7 Hearts 8 5 Diamond s 4 9 Clubs 8 5 26 26 (a) What is the probability that a card randomly selected from the We team’s hand is a spade? (b) What is the probability that a card randomly selected from the They team’s hand is a club? (c) What is the probability that a card randomly selected from all the cards is either a spade or heart? (d) What is the probability that a card randomly selected from all the cards is either a diamond or club? (e) What is the probability that a card randomly selected from the They team’s hand is not a club? What type of probability estimates are these?
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.
During a recent bridge game, once the lead card had been played and the dummy’s hand
revealed, the declarer took a moment to count up the number of cards in each suit with the
results given below:

(a) What is the
spade?
(b) What is the probability that a card randomly selected from the They team’s hand is a
club?
(c) What is the probability that a card randomly selected from all the cards is either a spade
or heart?
(d) What is the probability that a card randomly selected from all the cards is either a
diamond or club?
(e) What is the probability that a card randomly selected from the They team’s hand is not a
club?
What type of probability estimates are these?
