n urn contains 3 red balls, 4 green balls and 1 yellow balls. An experiment consists of picking 3 balls simultaneously. What is the probability that you pick at least 2 green balls
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.
An urn contains 3 red balls, 4 green balls and 1 yellow balls. An experiment consists of picking 3 balls simultaneously. What is the probability that you pick at least 2 green balls?
Given:
Number of red balls = 3
Number of green balls = 4
Number of yellow balls = 1
Total number of balls = 3 + 4 + 1
= 8
Number of balls picked = 3
