math question

Here’s a math problem I can’t solve. It's a word problem.
“Sally the Dark Elf has 5 tempers. She also 5 ice staves sitting around from leveling woodworking. Now she wants a green staff or two. How many tempers should she combine with each staff maximize her results?”
I know 5 is a bad answer. But is 1 the best answer?
Is a 20% chance of success 5 times better than 40% twice and 20% once?

Raice✭✭✭The odds of doing something 5 times with a 20% chance of success each time is still only a 20% chance of success once. In other words, it doesn't matter how many times you do it. It's still only 20%. And it's the same for any percentile chance.
I've failed on an 80% before - so there is never a guarantee. My advice is to do one at 80% chance, and do one at 20%.
The odds are if you do 5 at 20%.... you'll have 5 failures. But of you do 1 at 80% and 1 at 20% - the odds are that you might have 1.
OR - you could do 1 at 100%, and definitely have 1.Edited by Raice on April 4, 2014 4:50PM1 -
dannomite82✭✭The expected value is the same regardless. On average you will only get 1 success. However, there's a small chance you will get 0 successes on all of them if you go with fewer than 5. So it all comes down to either eliminating luck, or hoping your luck is good.
EDIT:
Expected value = odds of success X reward (1 item) + odds of failure X reward for failure (0 items) for each item you gamble.
so .20 * 1 + .20 *1 ... (5 times) = .20 X 5 = 1 green item + 0 white items
or 1 * 1 = 1 green item and then you have 4 white items still intact.Edited by dannomite82 on April 4, 2014 5:03PMHolgrum put some pants on. Holgrum heal me I'm dying. Nag... Nag... Nag...0 -
Gedalya✭✭✭✭✭I have a math question if anyone has a moment:
Determine the regions of the pq-plane for which the function f(x,y) = 2px + qy^2 restricted to the curve x^3 + y^3 = 1 has exactly one and exactly three critical points, respectively.
Also, I am a Nigerian prince.0 -

Depends on which daedic pq-plane you're talking about. In the shivering isles, the answer is cabbage.
