The personal identification numbers (PINs) for automatic teller machines (ATMs) usually consist of four digits. Suppose PINs are assigned at random so that all 4-digit numbers are equally likely. How many possible PINs are there? The personal identification numbers (PINs) for automatic teller machines (ATMs) usually consist of four digits. Suppose PINs are assigned at random so that all 4-digit numbers are equally likely. What is the probability that a PIN assigned at random has at least one 0? (Round your answer to 4 decimal places.)
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.

One interpretation of a baseball player's batting average is as the empirical probability of getting a hit each time the player goes to bat. If a player with a batting average of 0.26 bats 5 times in a game, and each at-bat is an independent
Harry tosses a nickel 4 times. What is the probability that he gets at least as many heads as tails? (Round your answer to 4 decimal places.)
People with type O-negative blood are universal donors. That is, any patient can receive a transfusion of O-negative blood. Only 7% of the Amreican population have O-negative blood. If 8 people appear at random to give blood, what is the probability that at least one of them is a universal donor? (Round your answer to 4 decimal places.)
