...If you throw a dice 6 times, what's the chance that you'd get a six on:
a: exactly one of the throws.
b: one or more of the throws.
?????

I hate odds and I hate probability.
I'm asking about the chance.Quote:

you may as well just make one big one.
Is it a fair dice? Or will it screw you and run off with your best friends wife as soon as its robbed you of all your money?
Wasn't that coin thing of Scrubs, but I cant remember what it was.
And for the dice: Theres a 1 in 6 (1:6) chance that you would get a 6. But I dont think anyone can work out B unless you say how many other throws there will be.
Wikipedia says chance is probability.Quote:

It says it will be rolled six times, and gives no indication that there would be no reason to stop rolling. So yeah, B is pretty easy, easier than A at least.Quote:

Assume X = rolling a 6 (also / indicates a fraction, ^ indicates exponent)
for a) P(X=1)= (6C1)(1/6)^1(1- 1/6)^6-1
= (6C1)(1/6)(5/6)^5
= (6)(1/6)(3125/7776)
= 3125/7776
Therefore the probability of rolling a 6 in exactly one of the six throws is 3125/7776
for b)
P(X > or = 1)= 1- P(X=0)
=1- ((6C0)(1/6)^0(1-1/6)^6-0)
=1- ((1)(1)(5/6)^6)
=1- ((1)(1)(.334897976))
=1-(.334897976)
= .665102023
Therefore the probability of rolling at least 1 six in six rolls is .665
Scrubs
one is a dime.
1/6 and 1/6
I make a) to be 3125/7776 = 0.402 (3sf)
b) comes out as 1 - (5/6)^6 = 0.665 (3sf)
Dice throwing isnt determined by chance, it is determined by skill, a random number generator on the other hand...
