Worked practice questions

Sabnam has 2 school bags, 3 tiffin boxes and 2 water bottles. Choosing one of each, she can carry them in:

  1. 14 ways
  2. 12 ways
  3. 7 ways
  4. 10 ways
Show answer and solution

Correct answer: B. 12 ways

1. Bags and boxes give 2 times 3, or 6 pairs. 2. Each pair takes 2 bottle choices. 3. That gives 12 ways. _Source: syllabus Mathematics, Chapter 7, Permutations and Combinations._

If one event can happen in m ways and then another in n ways, the pair happens in:

  1. m times n ways
  2. m plus n ways
  3. m minus n ways
  4. m over n ways
Show answer and solution

Correct answer: A. m times n ways

1. Each way of the first pairs with every way of the second. 2. So the counts multiply. 3. The total is m times n. _Source: syllabus Mathematics, Chapter 7, Permutations and Combinations._

Four letter words from the letters of ROSE, with no letter repeated, number:

  1. 16
  2. 24
  3. 12
  4. 36
Show answer and solution

Correct answer: B. 24

1. The first place has 4 choices, then 3, then 2, then 1. 2. Multiply those together. 3. The count is 24. _Source: syllabus Mathematics, Chapter 7, Permutations and Combinations._
