Was the horse question about mutation or variation?

Me too, would we get 1 mark as we just divided it the wrong way round?

Same. I'm reassured.

For the sense organ one would eyes be okay?

It was 0.6% recurring.

I remember the question.

It was 3*10^8 people get malaria and 2*10^6 died from it.

To work out a percentage you take the lower number and divide it by the higher number and then * by 100.

There you get

(2/3 * 10^6/10^8) * 100

2/3 * 10^6/10^8 is 2/3 * 10^-2.

This is 0.006 recurring.

However then you times by 100 since it is a percentage.

This leaves you with 0.6% recurring of people dying.

OH MY GOD I just realised how badly I hecked up that horse question, I didn't talk about genes at all cor blimey gee wiz I just talked about why longer legs were beneficial and stuff

edit for PG
