A company purchases machine components after randomly selecting 15 components and testing for defects. If the components have a 3% rate of defects, use the binomial distribution to find the probability of each: a) Getting no defects (x=0 ). b) Getting 2 or fewer (x ≤ 2 ) defects. c) Getting 3 or more (x≥3 ) defects.
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.

a) Getting no defects (x=0 ).
b) Getting 2 or fewer (x ≤ 2 ) defects.
c) Getting 3 or more (x≥3 ) defects.
d) Find the mean and standard deviation for the number of defects.
e) Would it be a rare
