Yes, you may recognise the answers. The questions that overlapped were at the end of your paper and at the start of ours.

Hope you've done well!
what was the stem and leaf diagram question worth?

We completed Unit 1 for the 4360 Modular specification, so don't worry; you did 4365 Linear.

Sorry I was given the question incorrectly, the median needed to be 8.5 not 7!

I have updated the post with a new (hopefully) correct answer of 7, 7, 10, 14

Phew! :smile: Thanks for letting me know! :smile:
This is actually wrong. You considered the following possibilities:
Centre, Miss (0.2*0.3=0.06)
Outer, outer (0.5*0.5=0.25)
However, what you failed to consider was the third possibility of missing, then hitting the centre, which would result in an extra 0.06, meaning your answer would be:
0.25+0.06+0.06=0.37

Question about card 'A' was 2

3/25 X 4 = 12/100
1/10 X 10 = 10/100
12/100-10/100 = 2
