Here is a good probability question from the 80s: A small town has 1000 telephone numbers consisting of the numbers 5000 to 5999 inclusive. a. How many of these numbers end in 3? b. You remember only that a friend's telephone number ends in 2 and has 4 as one (or both) of its two middle digits...

best thing you can have before the exam is sleep.

Look at the standard integrals sheet. Also derive secx and see what you get.

This. In 2U they just say "...and justify your answer".

Nice work :D

i got 10.90%. 44% is way too much, remember it's how much is NOT visible by one tower.

Well done and thanks. Thanks to carrot for checking it for me. Part 2:

nope you're correct for part b :D

Yeh i did, there is a second part that i will post as soon as i solve it.

no need to explain to me, i wrote the question lol just for people to have a go at but yes your right so far (and note what realisenothing said)

Are you doing the hsc exam for mx2?

Yeh that can happen. It's important to think about all possibilities. Another mistake is where given a question like this: Two cards are drawn from a deck of cards without replacement, what is the probability of drawing the same suit for both cards. Many would have got 1/17 because they don't...

If you draw up a table with the values for the red die up the vertical axis and the values for the white die on the horizontal axis, then mark/tick the combinations where the value for white is grater then that of red. You should get 14 out of the possible 36 combinations where white is greater...

Noticed similar threads for other subs, so why not 2u :)

Yeh i got the same for both. I would say it's the first because they would have stated "at least" in an exam question.

Or you could try primarily block but join letters occasionally to write faster, at least that's what we're told.

It sounds like reading your responses is a little time consuming too.
