In order to find the probability of both marbles being drawn being the same colour, the probability of each marble being drawn has to first be found and then multiply both probability to find the probability of two orange marble being drawn consecutively.

Now, the probability of drawing an orange marble = ⁴/₉

since a marble has been removed and wasn't replaced then there are now 5 pink + 3 orange marbles (8 marbles in total) in the bag.

∴ the probability of the second marble drawn being orange = ³/₈
⇒ the probability of two orange marbles in a row without the first being replaced = ⁴/₉ × ³/₈ = ¹/₆

In this item, we are given with the amounts of both the flour and sugar.

Part A:
First, we determine the total amount of recipes needed for the batch.
total amount = (4 1/5 cup) + (2 3/7 cup)
total amount = 232/35 cup

To determine the total amount of sugar needed for 4/9 of the recipe, we multiply the given amount of sugar by 4/9. That is,
amount of sugar = (4/9)(2 3/7)
 amount of sugar = 68/63 cups of sugar

Part B: To determine the amount of flour needed is 3 times the given amount for each batch.

amount of flour = (3)(4 1/5 cups of flour)
 amount of flour = 63/5 cups or 12.6 cups of flour
