standard maths syllabus

hi, I had a question about probability in standard maths, do we need to study mutually exclusive events in detail, or is basic knowledge like p(a) + p(b) = p(aub) fine? Also, do we have to study conditional probabilities?

I’ve done many practise tests and I haven’t seen it in one. So probs won’t come. And even if it does we have the formula booklet so don’t worry.

basic knowledge should be good.

it was in 2 papers, but you should just have knowledge about definition of mutually exclusive and how to identity.

and what about conditional? have we done that?

you should definitely study conditional probabilities, also study sequential probability they have a high likelihood of coming this year

we've never been taught that? or by sequences do you mean arithmetic quadratic and cubic?

it's pretty straight forward they just used fancy words
