Julie’s lolly bag contains two chocolates, two boiled lollies and a gum ball. She eats two of them, randomly, one after the other (that is, with no replacement.) a Use a simple tree diagram to represent this situation.
b What is the probability the lollies she eats will be a chocolate, followed by a boiled lolly?
c What is the probability both the lollies will be the same?
d What is the probability at least one of the lollies will be a chocolate?
e She decides that if the second lolly is the same as the first, she will replace it and try again until she gets a different lolly. What now is the probability at least one of the lollies will be a chocolate?
(Hint: There is no need to extend the tree diagram. Think of what this situation is
equivalent to.)

  1. 546 - 25 x 13 (divided by) 13

    546 - (25 x 13) / 13

    Step-by-step explanation:

    25 x 13 = 325

    546 - 325 = 221

    221 / 13 = 17

    17 mens teams can register.

  2. DISCOUNT = $5134.14SELLING PRICE = $10,423.86

    Step-by-step explanation:

    Discount = 33%cost price = $15,558discount = (33×15558)÷100 = 513,414 ÷ 100 = $5134.14Selling price = cost price - discount = $15,558 - $5134.14 = $10,423.86FOLLOW ME

  3. [tex]25(13)+13m\leq 546[/tex]


    Step-by-step explanation:

    Each team can only consists of 13 players. Therefore, the total number of players is represented by:


    Where w represents the amount of women's teams while m represents the amount of men's teams.

    The total number of players cannot surpass 546. In other words, it must be less than or equal to. Therefore:

    [tex]13w+13m\leq 546[/tex]

    We already know that 25 women's teams have already signed up. To find out the possible number of men's teams that can sign up, we can substitute 25 for w and then solve for m.


    [tex]25(13)+13m\leq 546[/tex]

    I believe the answer would be A (there's no inequality sign, so I'm not sure).

    This isn't required by the problem, but I'm going to solve it regardless. Subtract and simplify:

    [tex]325+13m\leq 546\\13m\leq 221\\m\leq 17[/tex]

    Therefore, the maximum number of men's teams that can still register is 17 teams.

  4. Of the blood component that would benefit from transfusions is the beta globin protein. Blood transfusions would be from one of their relatives, as long as they are not diagnosed with this same health condition, that is, they are healthy.


    Beta thalassemia is a type of hereditary thalassemia, characterized by a hematological disorder that reduces the production of healthy red blood cells and normal hemoglobin. Hemoglobin is an iron-rich protein found in red blood cells and is responsible for transporting oxygen to cells throughout the body. This protein has two parts: one is called alpha globin and the other beta globin. There are genes that control the way the body produces hemoglobin. When these genes are altered or missing, thalassemia occurs. The hemoglobin protein affected in beta thalassemia is beta globin.

    In the case presented, when both genes are altered, the person has beta thalassemia intermedia or beta thalassemia major (also called Cooley's anemia).

  5. $108.88 ( discount ); $221.07 ( selling price )

    Step-by-step explanation:

    33% = 0.33

    $329.95 × 0.33 = $108.88 ( discount )

    $329.95 - $108.88 = $221.07 ( selling price )
