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
Before we begin to understand the addition of algebraic expressions, we need to list out a few things that form the basis of algebra.
10 and 12
Given that
Total people selected (n) = 1114
Regular smokers = 162
Heavy smokers = 93
both heavy and regular smokers included = (162+93)=255
We know that
one person is randomly selected the probability it is either regular or heavy smoker.
Favorable events = 255
Total events = 1114
Probability =
If a person is drawn random the probability that regular or heavy smoker is 0.2289
