Answer:
Step-by-step explanation:
This is permutation, since order matters. The formula for us is
₁₈P₅ = which simplifies to
₁₈P₅ =
The factorial of 13 cancels out on the top and bottom leaving you with
₁₈P₅ = 18 × 17 × 16 × 15 × 14
which comes to 1,028,160 ways
Another way to look at it is: the first 5 people of 18 finish and the others you don't care about. Once the first place person is first, there are only 4 of the 18 left to finish in second place. Then there are only 3 left to finish in third place, etc. So if we use that reasoning, we don't even need to use the formula, we can just say
18 * 17 * 16 * 15 * 14 and those are the first 5 people of 18 to finish.
Answer:
-$ 10.13
Step-by-step explanation:
Given,
The cost price of each ticket = $ 22,
So, the value of each ticket other than price ticket = - $ 22, ( negative sign shows loss,i.e. if we don't get the price we will have the loss of $ 22 )
Now, there are 3 tickets in which first is of $35,000 price, second is of $1,100 and third is of $ 600,
So, the value of first ticket = 35000 - 22 = $ 34978,
Value of second ticket = 1100 - 22 = $ 1078,
Value of third ticket = 600 - 22 = $ 578,
Also,
Hence, by the above information we can make a table for the given situation,
Number 2997 1 1 1
Price -$ 22 $ 34978 $ 1078 $ 578
Probability 2997/3000 1/3000 1/3000 1/3000
Therefore, the expected value of a ticket
≈ - $ 10.13

Step-by-step explanation:
Observing the table we have
The actual salary is $3,600 -----> This amount represent the 100%
The actual total expenses are $3,455
using proportion
Find out what percentage of the actual salary are the actual total expenses
