  • What does it mean if the probability of winning a certain game is 0.5?
    It means there is an equal chance of winning or not winning the game; the event is as likely to occur as not to occur.
  • How do you calculate the probability of spinning an even number on a spinner with numbered sections?
    Count the number of even-numbered sections and divide by the total number of sections. Probability = (number of even sections) / (total sections).
  • What is the probability of an event that is impossible?
    The probability of an impossible event is 0.
  • How do you calculate the probability of drawing a 10 or a jack from a standard deck of cards?
    Add the number of 10s and jacks in the deck and divide by the total number of cards. Probability = (number of 10s + number of jacks) / (total cards).
  • What is the probability of an event that is certain to happen?
    The probability of a certain event is 1.
  • In mathematics, what does 'at least' mean?
    'At least' means greater than or equal to a specified value.
  • How do you calculate the probability of rolling an even number on a standard six-sided die?
    Count the number of even numbers (2, 4, 6) and divide by 6. Probability = 3/6 = 0.5.
  • Which values cannot be probabilities?
    Values less than 0 or greater than 1 cannot be probabilities.
  • How is probability best described?
    Probability is a measure of how likely an event is to occur, expressed as a number between 0 and 1.
  • What is probability?
    Probability quantifies the likelihood of an event occurring, ranging from 0 (impossible) to 1 (certain).
  • How do you calculate the probability of rolling a sum of 8 with two dice?
    Count the number of ways to get a sum of 8 and divide by the total number of possible outcomes (36 for two six-sided dice). Probability = (number of ways to get 8) / 36.
