Algebra is the branch of mathematics that helps in the representation of problems or situations in the form of mathematical expression. It involves variables like x, y, z, and mathematical operations like addition, subtraction, multiplication, and division to form meaningful mathematical expressions. Key Points In the above-given options, all the options except option 2 involve the operations of algebra. Option 1;- 100-5 =95, we have to distribute among 15 students so we divide by 15 so 95/15 we get 6 remainders. Option 3:- Plotting a graph involves x and y variables for which values are given in numbers, so this is also part of algebra. Option 4:- Here 10% is given as 1200 we have to find 100% that will be equal to 1200x10 = 12000, & this also belongs to algebra. But in option 2 the question is about the chance of getting candy, this question doesn't belong to algebra as it is a part of Probability. Hence the question in option 2 would be least relevant for the given purpose. Additional Information Probability is a branch of mathematics concerned with the analysis of random phenomena. The outcome of a random event cannot be determined before it occurs, but it may be any one of several possible outcomes. The actual outcome is considered to be determined by chance.
