  • Design a spinner where the probability of landing on blue is exactly 1/3.
    Any spinner with 3, 6, 9, 12, etc. equal sections where 1/3 of them are blue
  • What's the probability of rolling a number greater than 4?
    2/6 = 1/3
  • How many possible outcomes are there when rolling one die?
    6
  • What's the probability of getting heads when flipping a fair coin?
  • If you flip a coin 10 times and get 6 heads, what fraction
  • Convert 3/8 to a decimal.
    0.375
  • If you flip two coins at the same time, what are all the possible outcomes?
    {HH, HT, TH, TT}
  • A spinner has 4 equal sections. What's the probability of landing on any one section?
    1/4 or 25%
  • What is the sample space for flipping a coin?
    {Heads, Tails}
  • A spinner has 10 equal sections, 4 are green. What's the probability of NOT landing on green?
    6/10 = 3/5 = 60%
  • What's the probability of rolling an even number on a die?
    3/6 = 1/2 = 50%
  • True or False: The probability of getting tails is the same as getting heads.
    True
  • What's the probability of rolling a 4 on a fair die?
    1/6
  • If you roll a die 12 times, about how many times would you expect to get a 6?
    About 2 times (12 ÷ 6 = 2)
  • A spinner has 8 sections: 3 red, 3 blue, 2 yellow. What's the probability of landing on red?
