There are 10 urns, each containing 3 white and 7 black balls. A ball is accidentally pulled out of the first urn and transferred to the second, then a random ball is transferred from the second urn to the third, etc. At the end, a random ball is drawn from the tenth urn. Find the probability P of being white. Enter a number as a decimal fraction with a dot separator to one decimal place, for example 0.3.
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.
