A researcher had conducted a study at one the Orang Asli settlements in Pahang. He stays at one of the block of settlements which consist of 20 families. He learned that the probability of each of the family going to the river for their personal needs at least once a day is 0.40. Find the probability that a) At least, ¾ of the whole families would not go to the river at least once a day. b) Less than 10 families would not go to the river. c) From 6 to 12 families would go to the river at least once a day.
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.
