    Hello, I am confused on what the meaning is of the below: a cube has 6 sides, so division by 6 would be the model for probs, we need a division by 5 or 10 or 15 ,etc I understand that a cube has 6 sides but I am lost on the rest.

    Hello Michael the probability of pulling out a red coin for part c is 8/18=4/9 is this correct?
  33. Math

    Hello Michael so then my answer would be 9 out of 15. But if there are 14 coins total and like you said they took out 1 which would be 14 -1=13 plus 3 would that be 16 instead of 15?

    Hello Reiny: I am confused on prob(not ace or king) How do you actually go about figuring this out and can you explain this so I have a better understanding. Thank you
  49. Math

    Hello. I think I just figured this out. The odds of picking an ace or a king is: 8/52 (since there are 4 aces and 4 kings in a single deck, 4+4=8_ 8/52 can be simplified to 2/13 Answer=2/13
  50. Math

    There are 4 aces and 4 kings in a standard deck of 52 cards. You pick one card at random. What is the probability of selecting an ace or a king? Explain your reasoning. I am a bit confused on this one. Please help.
  51. Math

    Okay. Yes see what you are saying. There is also a different method in figuring it out is what you are saying.
  52. Math

    Ms. Sue really? Oh my goodness. I will explain to you how I figured this out. 4/52 I took 52-4 which equals 48 48/52=24/26=12/13 12/13 + 1/13=13/13
  53. Math

    Would the answer be 12 out of 13 or 12/13
  54. Math

    There are 4 queens in a standard deck of 52 cards. You pick one card at random. What is the probability of not picking a queen? This one is a bit confusing. 4/52=1/13 is the probability of picking a queen. I am not sure how to figure this one out.

    A spinner has 5 equal sections marked 1 through 5. What is the probability of not landing on 4. (1, 2, 3, 4, 5) 1/5 or 1 out of 5 is the probability of landing on 4 My answer: 4 out of 5 is the probability of not landing on 4. Is this correct?
  57. Math

    A bit more but I am going to study this more about the complements. Thank you
  58. Math

    A spinner has 3 equal sections that are red, white, blue. What is the probability of not landing on blue? My answer 2 out of 3 or 2/3 is the probability of not landing on blue. Is this correct?
  59. Math

    Hello Ms. Sue. I looked at website now that gave me more of an explanation. Complement is the opposite so 5 out of 6 would be the answer.
  60. Math

    The probability of rolling a 5 is 1/6 1 out of 6. They are saying to figure out the complement. What do they mean by this?
  61. Math

    The probability is 0 then
  62. Math

    Use the complement to find each probability. What is the probability of not rolling a 5 on a standard number cube? My answer is 1/6 since there are 6 faces Is this correct and if not can you explain on how to do this? Thank you
  63. Math

    Yes and no.

  67. Math

    Close to 1/2?
  68. Math

    I believe that the probability would be close to 0. If it were 50% then the probability would be 1/2 so my answer is close to 0.
