A coach has 6 players that will join track and field. The random variable that is being studied is X, the number of players that will win. The probability function for this variable is shown in the table below. X 1 2 3 4 5 6 f(x)=P[X=x] 0.40 0.24 0.19 0.1 0.05 0.03 Question1: Find the probability that the majority of the players will win the play? a) 0.72 b) 0.84 c) 0.52 d) 0.28 Question2: what is the probabilty that at most 2 will win the play? a) 0.72 b) 0.84 c) 0.52 d) 0.28
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.
