Rework problem 1 in section 4.2 of your text, involving the flipping of a loaded coin, but assume that Pr[H]=0.2. Also, assume that the coin is flipped 4 times, and the random variable X is defined to be 3 times the number of heads minus 2 times the number of tails. How many different values are possible for the random variable X? Answer:5 Fill in the table below to complete the probability density function. Be certain to list the values of XX in ascending order. Value of X Probability -8 -3 2 7 12 **Just need the Probability portion of the graph answered, all other answers provided are correct
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.
