Answer: 13 outcomes
Step-by-step explanation:
Given:
She wants to get a gift from the following choices;
- one of five books
- one of four ties
- one of four X-box
Since, the three groups of choices are joined with "OR" but not "AND" that means she is getting just one gift from any of the 3 groups.
Total number of gift she needed = 1
Total number of choices = 3 groups with total of 13 options
N = 13P1 = 13!/(13-1)! = 13!/12! =13
N = 13 outcomes.
