Rework problem 31 in section 4.2 of your text, involving the selection of two numbers. Assume that you select two 4-digit numbers at random from the set of consecutive integers from 0000 through 9999. The selections are made with replacement and are independent of one another. If the two numbers are the same, you make $700. If they are different, you lose $4. A random variable X is defined as your gain or loss. 1. How many different values are possible for the random variable X? 2. Fill in the table below to complete the probability density function. Be certain to list the values of X in ascending order. Enter a loss as a negative number.
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.
