20. A coin has an equal probability of coming up heads or tails when tossed. Suppose a game is played where a player is awarded 10 points if a pair of tosses both come up heads, 8 points if they both come up tails, and 2 points if the result is 1head and 1 tail. What is the expected value of the score for a pair of tosses? GeoGebra Graphing Calculator a.5.55 b.5.95 c.6.36 d.6.7
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.
