We simply had to calculate the selections;which were 10.Aha exactly 10 selections and 60 arrangements I got only 9 selections that's why I got only 54 arrangements. What I did exactly is that I wrote the arrangements under each selection but I didnt multiply by 3! I dont think there is a difference right ?? Anyway then I found that there are 30 selections out of 54 where the smallest number is 1 and then 18 out of 54 with smallest number 2 then only 6 out of the 54 with the smallest number 4 so apparently the number of arrangements I got where the smallest number is 2 or 4 is right but 1 is not right as it should have been 24 instead of 18 so yeah I hope I would get those 3 marks as you said because I really wish that I can get the star in the Math Alevel and el7amdullah all the other questions are totally right .
Note them down starting with 1 then 2 and then 4.
We had to write probabilities for only 1,2 and 4 as they can be the smallest digits in each selection.
There were 6 with 1 smallest
3 with 2
1 with 4.
Probability table: 0.6,0.3,0.1.
You will get 2 at max.
You didn't get the selections right.You didn't get the arrangements right either.You used the wrong information.Got wrong probabilities.
I think 2 is the max you can get but considering how tough the checking is in a levels,you never know!
