Kyx's Puzzle Palace Mk I

Each room contains one puzzle. By completing each puzzle, you move onto the next room. Work as a team, guys.
Room 1 - The Missing Pound Room
Kyx, the penguin at the counter, is approached by three other penguins. They order a supersized bowl of noodles. This costs £30.
Kyx: I'll tell you what: if you manage to eat this in under ten minutes, I will give you a £5 discount.
The penguins manage to eat the noodles in 9 minutes 59.999 seconds.
Kyx: Well, you just about did it. Have this £5 note.
Penguins: We can't split that evenly between us three. Give us £3, and you keep the extra £2.
Kyx: No problemo
Here's the problem: Each penguin has now contributed £9 towards the bowl of noodles, which makes £27. Kyx has another £2, which brings the total to £29. What has happened to the other pound from the original £30?

we can do this matrix!
together!

At first, they paid £30, or £10 each. Then, £5 was taken off the bill, so the meal cost £25. However, @Kyx kept £2 for himself.

There is no missing pound! The penguins, somehow able to handle coins with their flippers, spent £27 (£9 each): £25 on the meal, and £2 for the service charge.

The initial £30 was broken down into:
£25 paid for the noodles
£3 back to the penguins
£2 for Kyx

Or:
£27 total cost
£3 back to the penguins.

Room 2 - Probability of the girls

Kyx and Flyx have two baby penguins. If one of them is a female, what is the probability of the other being a female too?

I think I have an answer:

50%........

1/2 is NOT the correct answer

1/2 is NOT the correct answer

OK, let's see:

2 penguins, A and B. m= male, f=female

One must be female, hence the possibilities are:

A........B
f.........m
f.........f
m........f
f.........f

Aha! Combination f...f is repeated! It seems that if A is female, there are 2/3* (EDIT) chance B will be female, and vice versa...

Not sure what to make of this.
