A child is playing with number blocks. She has nine blocks, numbered 1 through 9. a) If she selects three blocks at random from the nine blocks and puts them to the side, what is the probability that she selects the 1, 2, and the 3? b) If she selects three blocks at random from the nine blocks, and lines them up to make a three digit number, how many possible three-digit numbers are there?
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.
