You seem to know a lot about mathematics (and i personally suck at probability) so could you be a lamb and explain this question to me. If 10 coins are tossed 50 times, in how many cases would we expect the number of heads to exceed the number of tails? (Ans: 19) Much appreciated, take however you long you need.
I'm a parent. My daughter is choosing Yr 12HSC subjects and I'm worried. She's clever but chooses easy options. Dropped Maths. Doing Advanced English, Visual Arts, Biology, PDHPE, Italian Bgns., likes all her subjects. Needs ATAR of 80 for either direction in 2020; the arty way or Human Sciences way (she's sporty). Can you comment on how achievable an ATAR of 80 via those subjects might be, please?
