Question

HELP!! Jenna has a bag of 4 marbles: 1 red, 1 blue, 1 green, and 1 purple. Make a sample space for Jenna picking two marbles at a time. How many outcomes are there? A) 4 B) 6 C) 8 D) 12

Answer 1

Answer=12

The first marble has 4 outcomes, 1/4. The second marble only has 3, since the first one is now gone, 1/3.

1/4*1/3=1/12

12 outcomes

Answer 2

You have 4 marbles and you can get 3 combinaisons of two marbles for each one. 

So 4*3 = 12.

There are 12 outcomes. The answer would be D.

Hope this helps !
