8. Suppose there are three crucial components on a space shuttle launch: rocket system, guidance system, and communications system. Suppose also that the probabilities that the systems function correctly are Rocket, 0.95; Guidance, 0.9; Communications, 0.99. If one or more of the components does not work, the launch must be aborted. (We are not taking into account backup systems.) 2. What is the probability that a launch will be aborted? What assumption must you make to determine this probability, based on the information you

Algebraic Expressions

In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.

Numbers

Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.

Subtraction

Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.

Addition
