An eiectrical system consists of four compobents as illustrated in the figure. The system works if companents A arnd B work and either of the components Cor D works. The reliability (probability of working) of each component is also shown in figure. Determine a) The prohability that system works b) The probability thut the component D does not work, given that the entire system works. c) The probability that the component B does not work, given that the entire system works. Assume that the four components work independently. 10 10 10 A 10 DE N/2

Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
