Hi I'm stuck on question 6b. The teachers tried explaining but not in a way I understand, does anyone have simple logical way of answering it?
Thanks in advance!

Link the paper. We don't know what exam board you're on.

These are the Edexcel model answers assuming that's your exam board

Is it normal distributions you don't understand or conditional probability?
