Create a scenario involving drawing 2 balls from a bag. There are different colours, but there can be several of the same colour.

A) Create a probability question such that the compound event of drawing the two balls is:
1. made up of independent events.
2. made up of dependent events.
3. made up of either independent or dependent events but has more than one way to happen (multiple cases).

B) Solve the probability question from A)

Note: You should have in A) 3 different probability questions, based on the same scenario!

This response includes 3 different probability questions based on the scenario of drawing two balls from a bag, and provides step-by-step solutions for each question.

B) Solve the probability question from A):

b) P(Drawing a blue ball and then drawing a red ball) = (3/5) * (2/4) = 3/10

c) P(Drawing a green ball and then drawing a yellow ball) = (4/10) * (6/9) = 4/15

d) P(Drawing one white ball and one black ball) = ((2/9) * (3/8)) + ((3/9) * (4/8)) + ((4/9) * (3/8)) = 19/36

Step-by-step explanation:

A) Create a probability question such that the compound event of drawing the two balls is:

Independent events: Suppose there are 3 blue balls and 2 red balls in the bag. What is the probability of drawing a blue ball and then drawing a red ball?

Dependent events: Suppose there are 4 green balls and 6 yellow balls in the bag. What is the probability of drawing a green ball, not replacing it, and then drawing a yellow ball?

Multiple cases: Suppose there are 2 white balls, 3 black balls, and 4 gray balls in the bag. What is the probability of drawing one white ball and one black ball?

B) Solve the probability question from A):

b) P(Drawing a blue ball and then drawing a red ball) = (3/5) * (2/4) = 3/10

c) P(Drawing a green ball and then drawing a yellow ball) = (4/10) * (6/9) = 4/15

d) P(Drawing one white ball and one black ball) = ((2/9) * (3/8)) + ((3/9) * (4/8)) + ((4/9) * (3/8)) = 19/36
