Answer:
2/9
Explanation:
First step is to understand the question. Brian can choose 3 different color shirts and 3 different color pants.
First part asks you to choose which list has all the different outcomes.
Second part asks you what the probability of choosing a white/gray shirt with black pants.
Third part asks you to plot the probability on the number line.
Brian 3 different shirt each can be matched with 1 of the three color pants.
Ex:
- Brian can choose white shirt and black pants
- Brian can choose white shirt and grey pants
- Brian can choose white shirt and navy pants
Now, repeat this with the gray and blue shirt and choose the list that has all this shirt and pant combo. (notice List2 is missing white shirt and navy pants combo)
After choosing List1, find and count the desired outcome asked in part2: choose a gray or white shirt and black pants.
There are 2 outcomes out of the total 9 outcomes or 2/9.
For part3, plot 2/9 on the number line.
