Questions and Answers

What is the primary purpose of a probability value?

  • To guarantee the occurrence of an event
  • To predict the likelihood of an event (correct)
  • To calculate the exact outcome of an event
  • To ignore the possibility of an event

    • What is the formula to calculate the probability of a simple event?

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

    • What is the format of a probability value obtained by multiplying the fraction by 100?

  • Ratio Format
  • Decimal Format
  • Percentage Format (correct)
