Basically, its alternatesegment theorem to get 51 on the part of the shape thats touching the tangent, then you subtract that from 90 to get 39.


apparently alternate segment is wrong.

It said AT LEAST one loss, so you work out P(W,L + L,W + L,L).

Hi guys

[This is an edited version of my earlier post]

I've done a full set of worked solutions and marks for the paper. However to avoid compromising school plans for the use of this paper, I'm now only making it available via PM. If you want a copy contact me and confirm you are a Year 11.

Thanks and apologies to schools who I may have upset.

For number 2 i thought it asked for it as a mixed number??

itias a mixed number the whole is 4 and the fraction is 7/8 which is 39/8 as improper

Reconsider your answer to the Venn probability question - actually Q.5 on the paper.

6/10


it is 7/10 - 1, 4 and 9 are only square numbers so B is 3/10, but it asked for not be so its the rest so 7/10
