    why are there two pass n fail 10:27 for English n one for maths?

    • @1stClassMaths
      @1stClassMaths  8 месяцев назад +1

      This is because we need to consider all the possible options. The top part of the branch is passing maths but then after this you could pass or fail English. The bottom part is fail maths then you could pass or fail English.

    In the “find the probability one of the counters is red why did you not use the path of red and red?

    • @1stClassMaths
      @1stClassMaths  7 месяцев назад +5

      Because that would be two reds, not one.

    Bag A contains 10 marbles of which 2 are red and 8 are black. Bag B contains 12 marbles of which 4 are red and 8 are black. A marble is drawn at random from each bag.
    1. Draw a tree diagram to show all the outcomes of the experiments.
    2. Find the probability of getting a red marble and a black marble.

    In the Lauren problem the not 5 outcome is wrong it should to P(even)=3/5 and P(odd)=2/5. Please explain

    • @1stClassMaths

    • @JuniorUziogon.Uz23
      @JuniorUziogon.Uz23 4 месяца назад

      I don't think we can take the five off the dice...yeah we rolled "Not 5" but it's still a probability that we could get a 5 on the second roll so that's why it's still P(even)=3/6 and P(odd)= 3/6
