Question

Part 1: Using your own words, describe two events that are independent. Use math vocabulary that you have learned so far in this module to explain what it means when events are independent.
I really hate these type of question. @mathstudent55 can you help?

Answer 1

How can I possibly know the vocabulary you have learned when I have no access to your learning materials?

Answer 2

Lol, sorry. I just assume because probability is more about looking at a chart. But can you explain to me what an independent event is?

Answer 3

Ok. Now at least you're learning probability.

Independent events are events in which the outcome of one event is not affected by the outcome of another event.

Here is an example.
You have a bag with 4 marbles, one each: white, blue, red and green.

Answer 4

You are going to draw two marbles.
What is the probability that you will draw the green one followed by the blue one?

Answer 5

won't is be a 25% chance?

Answer 6

If after you draw one marble, you do not replace it, and then you draw the second marble, then the two drawings are not independent because the drawing of the first marble will affect the outcome of the second drawing.

Answer 7

If, on the other hand, after you draw the first marble, you replace it in the bag, then you do the second drawing, then the second drawing is exactly like the first drawing, and the outcome of the first drawing does not affect the outcome of the second drawing. When there is replacement, the events are independent.

Answer 8

So by replacing what you take, will not effect the outcome making it independent

Answer 9

You are correct.
