Can you not bring in gcse maths to an a level section? That's nothing to do with this exam and you'll unnecessarily scare and panic people.

It's an unusual probability question and something similar could definitely come up on this exam, I appreciate it lol

Mean is affected by everything in the code ... so inverse

standard deviation only affected by multi/divison
6.60/1.4

How do you know what to equate to etc?
