Answer: See explanation
Step-by-step explanation:
Your question isn't complete but let me give different scenarios to help you solve.
Firstly, assuming we want to calculate the amount of items left after the large items are carried alone, this will be:
= 561 - 36
= 525
Secondly, if we want to know the percentage of the large items that will be carried alone. This will be:
= 36/561 × 100.
= 6.42%
Thirdly, if you want to know the percentage of the items that will be left after the large ones have been carried alone. This will be:
= 100% - 6.42%
= 93.58%

Answer:
(a) 10!
(b) 9!
(c) 2!9!
Step-by-step explanation:
(a)
Total number of members = 10
We need to line up the ten people.
Total number of ways to arrange n terms is n!. Similarly, total number of ways to line up the ten people is

Therefore the total number of ways to line up the ten people is 10!.
(b)
Let groom is immediate left of the bride it means both will sit together. So we need to arrange peoples for total 9 places (8 of others and 1 of bride and groom).

Therefore the number of ways to line up the ten people if the groom must be to the immediate left of the bride in the photo is 9!.
(c)
Let groom is immediate left of the bride it means both will sit together. So we need to arrange peoples for total 9 places (8 of others and 1 of bride and groom).
Bride and groom can interchange there sits.
Total number of ways to arrange bride and groom = 2!

Therefore the number of ways to line up the ten people if the groom must be next to the bride (either on her left to right side) is 9!2!.
So
a. so 100-1/10 of 100 or 100-10=90
then second dose minus 10% or 90-9=81
third dose 81 minus 10%=81-8.1=72.9
fourth dose 72.9 minus 10% or 72.9-7.29=65.61
so after 4th dose only 65.61% are left
b. so to get it to 5% you do alot and find that it takes 27 tries to get the percent down to 5.2% and 28 doses to get it to 4.7%
