Questions and Answers

What is a probability value in the context of simple events?

  • A prediction of the likelihood of an event occurring (correct)
  • A mathematical formula for calculating outcomes
  • A guarantee that an event will occur
  • A graph used to visualize probability distributions

What is the formula for calculating the probability of a simple event?

  • P(event) = total number of possible outcomes - number of ways in which an event can happen
  • P(event) = number of ways in which an event can happen + total number of possible outcomes
  • P(event) = total number of possible outcomes / number of ways in which an event can happen
  • P(event) = number of ways in which an event can happen / total number of possible outcomes (correct)

What is the percentage format of a probability value obtained by?

  • Multiplying the fraction by 100 (correct)
  • Adding 100 to the fraction
  • Dividing the fraction by 100
