Question

Elementary Statistics problem. List all the possible two-course selections. I don't know what it is to be honest. Can someone explain this to me. Thank you

Answer 1

There's only 6 different classes.

Answer 2

6 * 5 = 30.

Answer 3

For the other (a), I assume you click all the ones which do not have the same class together.

Answer 4

@Vuriffy tried to simply click on the ones that don't have same class together, and still can't pass this question. Any other hints?

Answer 5

it gave me a new set of numbers to work with after I kept getting the wrong answer. please help if you can. Thank you.

Answer 6

Only click the ones who have all three different values. See if it works for the three-course situation.

Answer 7

I honestly don't see any other way to combat this problem.

Answer 8

Now for (b) you have to do the diagram with the classes and then multiply all 3 ratios for your final answer.

Answer 9

(Probability). I am really tired right now, and need to sleep, so I am sorry I couldn't help any further. Try some help from someone else, I may just not be seeing it, because it's been a few months since I have touched base on this so I am pretty fuzzy on it.
