Answer:
The first 4 guests can arrive in 32,760 ways.
Step-by-step explanation:
The order in which the guests arrive is important. For example, A,B,C,D is a different outcome to B,A,C,D. So we use the permutations formula to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
![P_{(n,x)} = \frac{n!}{(n-x)!}](https://tex.z-dn.net/?f=P_%7B%28n%2Cx%29%7D%20%3D%20%5Cfrac%7Bn%21%7D%7B%28n-x%29%21%7D)
In this question:
4 guests from a set of 15. So
![P_{(15,4)} = \frac{15!}{(15-4)!} = 32760](https://tex.z-dn.net/?f=P_%7B%2815%2C4%29%7D%20%3D%20%5Cfrac%7B15%21%7D%7B%2815-4%29%21%7D%20%3D%2032760)
The first 4 guests can arrive in 32,760 ways.
Remember, a/(c/d)=(a)(d/c)
subsitute 1/2 for x
Answer:
142 is the answer of this your homework
Answer:
5
Step-by-step explanation:
Convert the element to fraction:
/ ![\frac{2}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B5%7D)
Switch the division to multipl:
2/1 * 2/5
Cross multiply:
2 is elimiated and 1 and 5 remain.
Answer is 1/5 which is 5.
