A lab network consisting of 15 computers was attacked by a computer virus. This virus attacks each computer with probability 0.25, independently of other computers. Let X be the number of computers attacked by the virus. c) Compute the standard deviation of the number of computers attacked by the virus.
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.
3) A lab network consisting of 15 computers was attacked by a computer virus. This virus
attacks each computer with
the number of computers attacked by the virus.
c) Compute the standard deviation of the number of computers attacked by the virus.
