In each of the examples that follow, determine what value the random variable would assign to the specific outcome listed. You have some number of coins in your pocket, and you choose two at random. The random variable ZZ assigns the value of the coins in cents to each outcome. What value is assigned when you draw out a quarter and a dime?
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 each of the examples that follow, determine what value the random variable would assign to the specific outcome listed.
- You have some number of coins in your pocket, and you choose two at random. The random variable ZZ assigns the value of the coins in cents to each outcome. What value is assigned when you draw out a quarter and a dime?
- A coin is flipped three times. YY is a random variable that assigns 3 times the number of heads flipped minus 2 times the number of tails flipped. What number is assigned to HHT?
- A person picks a number between 1 and 272820. The random variable ZZ assigns the 0 to an even number and 1 to an odd number. What number is assigned to 270221?
