Maths Paper 4 Discussion

last page equation was 1/20 n (n-14), its actaully easy, i did this in order to get 1/p x 3 (3 - q) = 2, and solved like leaner equation and last question answer (last part) was 300

2nd variant n=3 was a triangle and total no. of diagnols was 0 & 2 was for n=4 may be u overlooked

S*** ! i solved the adult and children question as a ratio ! the exam was hard ! i think i might not even get a C =(

[XPFMember]

but they might sometime give full marks if ans. is 100% correct but 0 if its wrong and no working is shown otherwise u can gain marks 4 correct working & wrong ans. but usually no working needed if question is for 1 mark

ZiadOwns you answer to the formula is actually wrong so you last paper was all wrong the formula will be 1/2n(n-3) as p=2 and q=3 and the last question in sequence was 31 not 300

 

[Romeo10]

Yes that's right . p=2 q=3 but i want to check the answer of the last probability question?? (no. of spins ) write the answer and the working ...

 

[karimehab]

(4/6)power n-1 x 2/6= the probability he gave you in the exam paper i donot remember it !

answer=5
