During winter it rains on average 18 out of 30 days. Five winter days are selected at random. Find, correct to four decimal places, the probabiity that:

a) the first two days chosen will be fine and the remainder wet,

b) more rainy days than fine days have been chosen

Let each different arrangement of all letters of DELETED be called a word.

i) how many words are possible

ii) in how many of these words will the Ds be separated?

I have already figured out part i), that bit was straightforward.. I'm just having extreme difficulties with part 2!

Any songs/bands that are similar to Arctic Monkeys, Children Collide, Blur, Nirvana, Dandy Warhols, Red Hot Chilli Peppers- or even something more chilled like Echo Movement? Or even some amazing, fantastic albums that are similar, semi-unheard of?

So, I've only been going out with my boyfriend for about 4 months.. but he always says "we're going to get married," and at first I was a bit creeped out because usually I am not the sort of person who has relationships and everything planned out and stuff, but he says it so frequently and you know when someone says things often you start to believe it?

yea, pretty much i wanna know why boys would say that to girls...

p.s im 16, he's 17- so it's way to early to be thinking about marriage.. :S

Hi there,

I was just wondering if anyone out there would be able to help me out here... I'm 16 years old and have been in an active sexual relationship for the past three months, and today is exactly 8 days after my period should be due. I know straight away that's ringing alarm bells for pregnancy and what not, so on the first day my period was due I took a home pregnancy test which told me I wasn't pregnant. Obviously I was relieved, but my period still had not come. I took another home pregnancy test (different brand as well), 4 days later and again the result was not pregnant. By this stage I wasn't worrying too much, just waiting for my period to come (which it still hasn't) but today is the 8th day after I am due for my period. I took another pregnancy test (a different brand to the previous two) about half an hour ago, and yet again the result is not pregnant.

Now, I guess I'm getting a little paranoid.. where is my period and why is it so late?

About one week after my last period, I had taken the morning after pill after suspicion the condom might have leaked. I haven't received it since then, it couldn't be a side effect could it?

Also, I'm noticing a bit of a discharge in my underwear that smells slightly of chlorine... please help :)
