Vocaloid:

first use the random numbers to generate the first 5 unique digits let me know what you get

zarkam21:

what do you mean can you explain further please :(

Vocaloid:

each digit represents one student read off the first digit then read off the next digit keep going until you have 5 unique digits

zarkam21:

12024

Vocaloid:

the digits must be unique

Vocaloid:

no repeats

zarkam21:

61475

Vocaloid:

no, go back to the begininng

Vocaloid:

12024 discard the second 2 and move to the next digit so you get 12045 make sense?

zarkam21:

Yes A little bit

Vocaloid:

now, starting where the first segment left off, generate 5 new unique digits

zarkam21:

58976?

Vocaloid:

where are you getting 8 from

zarkam21:

didn't you say that you get the number from the next unique

Vocaloid:

next sequentially, not numerically

Vocaloid:

we have 59766 we get rid of the duplicate 6 then we go to the next digit (the next one in the problem) it's a 1 so our next digits are 59761 make sense?

zarkam21:

yes

Vocaloid:

keep going with the next 5 digits

zarkam21:

70526

zarkam21:

62179

zarkam21:

71804

zarkam21:

right?

Vocaloid:

after the 1 the next digit should be a 4

Vocaloid:

47570 remove the duplicate 7's 475 now we use the next 2 available digits

Vocaloid:

72 the 7 is a duplicate from what we had before so we go to the next digit which is a 6

Vocaloid:

so we get 47526

Vocaloid:

this brings us right to the 5th segment (starting with 254) generate the next 5 digits

Vocaloid:

still there?

zarkam21:

Yes I am here trying to understand

zarkam21:

Yes I see

Vocaloid:

I need to start heading home now so let me type out the rest of the instructions

Vocaloid:

once you have finished generating the digits (use up all the available numbers), observe each set of numbers and see how many of the groups have 3 or more digits that are 1-5) and divide that by the total number of groups you obtained

zarkam21:

4 numbers have 3 or more digits that are 1-5

zarkam21:

Is the answer 46%

zarkam21:

@Vocaloid

zarkam21:

@Vocaloid

Vocaloid:

how many total sets of 5 digits did you get

zarkam21:

12024 : 4 - 1224  55976 : 2 - 55  61475 : 3 - 145  70726 : 1 - 2  25408 : 3 - 254  62279 : 2 - 22  71874 : 2 - 14  03499 : 2 - 34  92659 : 2 - 25  26041 : 3 - 241 

Vocaloid:

again, for each cluster of digits there should be NO duplicates

zarkam21:

4?

Vocaloid:

re-generate the clusters such that there are NO duplicates in each cluster each set of digits should have 5 unique digits (NO duplicates)

zarkam21:

OKay let me write it all out on scrap paper hold on a sec

Vocaloid:

@sillybilly123 do you know if I'm interpreting this problem correctly? I am treating each digit as 10% of the population (mutually exclusive with each other) so each digit within each of the 5 clusters must be unique

zarkam21:

when you say we use the next two available digits after removing the duplicate, do you mean in the next number or the current number?

Vocaloid:

what do you mean?

Vocaloid:

@sillybilly123 but if we allow duplicates it just ends up being 40% seems closer to what they want

Vocaloid:

|dw:1506526575483:dw|

zarkam21:

and then we would divide right?

Vocaloid:

I end up getting 6/8 (not sure if this is right)

Vocaloid:

I would probably just use your method

zarkam21:

OKay so just to go over this I would start from the beginning and the first number 12024 does have a duplicate. it has 2. So I would emit the second 2 and get 5?

Vocaloid:

right but I don't think my interpretation was correct

Vocaloid:

just use the clusters given in the problem and forget about the duplicate removing

zarkam21:

SO just forget about the removing and focus on the original numbers given

Vocaloid:

right (sorry if that was misleading)

Vocaloid:

I end up getting 4 out of 10 clusters so 40%

zarkam21:

Yeah okay thanks

zarkam21:

No its okay sometimes it is confusing

zarkam21:

I appreciate all your help always
