age bits and 8% show deviation with worn bits. If 20% of the holes are made with new bits, 70% with average edges and 10% with worn ones. a) What is the probability of having drift holes? b) What is the probability that the defective hole was made with a new bit?
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.
The size of a hole depends on the edge of the bit used, only 1.5% of holes with a new bit show deviation, 5% show deviation with average bits and 8% show deviation with worn bits. If 20% of the holes are made with new bits, 70% with average edges and 10% with worn ones.
a) What is the probability of having drift holes?
b) What is the probability that the defective hole was made with a new bit?
