Pretty freaking big.

A quick search turned up nothing, and I don't have the time to delve too deep. Honestly, just looking it up would be the best (unless somebody else has it ready).

Nope, I'm just a freshman in high school anyways, but I hope to by the end of senior year.

3/4{4}

3/{4*4} (by changing 4 to its inverse of 1/4, you have a like denominator)

3/16

Or ride your bike around the haaaaaalls?

(Provided I have like a half-hour, I could probably sing this and post it here.)

As a Potterhead, this Peeves me. The only cores are the heartstrings of a dragon, the feather of a phoenix, and the hair of a unnicorn.

Holly wood is 5/20, or 1/4

Dragon scale is 4/20, or 1/5

Add the two together.

5/20 + 4/20 = 9/20

However, do consider that there is one chance of those 'nine' that it can be both, and since the problem asks for 'or', take that out.

9/20 - 1/20 = 8/20 = 2/5

P(A or B) = 9/20

I'm going to assume this is a cube die?

1) 1/1 , 1/6 , 1/6 = 1/1*6*6 = 1/36

2) 5/6 . 5/6 , 5/6 = 5*5*5/6*6*6 = 125/216

3) 1/2 , 1/3 , 1/6 (considering that 2 , 4 , and 6 are your even numbers) = 1/2*3*6 = 1/36
