(Round your final answer to five decimal places) A box contains 23 integrated circuits, 4 of which are defective. If 4 are sold at random, find the following probabilities. (a) Exactly 2 are defective. (b) None is defective. (c) At least 1 is defective
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.
(Round your final answer to five decimal places)
A box contains 23
(a) Exactly 2 are defective.
(b) None is defective.
(c) At least 1 is defective
Given,
Number of integrated circuits=23
Number of defectives=4
Probability of defective circuit is p=
Size of sample n=4
Ley X=Circuit is defective
a) Probability that Exactly two are defective:
Thus, the probability that Exactly two are defective is 0.12382.
