Since this is a combination not a permutation problem, (order does not matter) you should use the "n choose k" formula.
C=n!/(k!(n-k)!) where C is the number of unique combinations, n equals the total number of possible choices and k equals the specific number of choices. In this case:
C=9!/(4!(9-4)!)
C=9!/(4!5!)
C=362880/(24*120)
C=362880/2880
C=126
So there are 126 unique ways to pick 4 people from a group of 9 people.
Answer: The other person eats 5/6ths of a pizza
Step-by-step explanation:
put it into sixths
The three angles are 45, 75, and 60. The sides across from these angles correspond to the length of the sides. Since 45 < 60 < 75, MN < ON < MO. The answer is therefore C. MN, ON, MO.
Hope this helps!
