In a child’s game, a spinner has 12 equal-sized sections. 1 section says “move ahead 3 spaces” 3 sections say “move ahead 2 spaces” 4 sections say “move ahead 1 space” 1 section says “lose a turn” 2 sections say “move back 1 space” 1 section says “move back 2 spaces” What is the expected value of one spin? Interpret “move ahead” as a positive move and “move back” as a negative move. a) 9/12 = 0.75 b) 3/12 = 0.25 c) 9/11 = 0.81 d) 8/12 = 0.6
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.
In a child’s game, a spinner has 12 equal-sized sections.
1 section says “move ahead 3 spaces”
3 sections say “move ahead 2 spaces”
4 sections say “move ahead 1 space”
1 section says “lose a turn”
2 sections say “move back 1 space”
1 section says “move back 2 spaces”
