Worked practice questions

Tossing two distinguishable coins can end in:

  1. Two ways
  2. Six ways
  3. Ten ways
  4. Four ways
Show answer and solution

Correct answer: D. Four ways

1. Each coin can turn up either a head or a tail. 2. The two coins can be told apart, so order counts. 3. That gives four outcomes in all. _Source: syllabus Mathematics, Chapter 16, Probability._
