Worked practice questions

Probability based on the results of actual experiments is called:

  1. Empirical probability
  2. Classical probability
  3. Impossible outcome
  4. Certain outcome
Show answer and solution

Correct answer: A. Empirical probability

1. It counts trials in which the event happened. 2. It is also called experimental probability. 3. Tossing a coin 1000 times gives such estimates. _Source: syllabus Mathematics, Chapter 15, Probability._

A coin tossed 1000 times gave 455 heads. The empirical probability of a head was:

  1. 0.055
  2. 0.455
  3. 0.545
  4. 0.500
Show answer and solution

Correct answer: B. 0.455

1. Divide 455 by 1000. 2. That gives 0.455. 3. Tails gave 0.545. _Source: syllabus Mathematics, Chapter 15, Probability._

  1. 2048
  2. 5067
  3. 12012
  4. 1024
Show answer and solution

Correct answer: A. 2048

1. The experimental probability was about 0.507. 2. The count was 2048. 3. Kerrich got 5067 heads in 10000 tosses. _Source: syllabus Mathematics, Chapter 15, Probability._
