1/3
Step-by-step explanation
(1/3)2x(1/3)-1 _ (1/3) 2-1 _ subtract 2-1 _ (1/3)1 take the one away bc any expression raised to the power of one equals itself
For this one you have to add all of the numbers. 5.5 plus 6.5 plus 4.5 plus 2.75 which equals to 19.25. Then you, 19.25/4=4.8125. All i did was turn the fractions into decimals to make it easier and do the math.

Step-by-step explanation:
As the complete question is not given a similar question is found online and is attached herewith.
Part a: Number of ways in which 12 candidates can be appointed for President, Chief Executive Officer, Chief Operating Officer and Chief Finance Officer.

Number of Posts=4
As the order is important the number of ways are identified using Permutations given as

So the number of ways in which the candidates can be appointed on the executive posts are 11880.
Part b: Number of ways in which 12 candidates can be appointed as members of the planning committee.
Number of Candidates=12
Number of Posts=4
As the order is not important the number of ways are identified using Combinations given as

So the number of ways in which the candidates can be appointed as members of the planning committee are 495.
