Best ResponseYou've already chosen the best response.1The whole roll 2n+1 times, get k even numbered die is a binomial distribution but I wonder

Best ResponseYou've already chosen the best response.1if the symmetry of the probability can't make this a bit easier.

Best ResponseYou've already chosen the best response.1We can definitely use the fact that it is multiple choice though...

Best ResponseYou've already chosen the best response.1If \(n=0\) then clearly getting an even face means you win, so the probability is \(1/2\).

Best ResponseYou've already chosen the best response.0i am getting d as the answer , but the book is saying a.

Best ResponseYou've already chosen the best response.1When \(n=1\). what is the probability?

Best ResponseYou've already chosen the best response.1You have three rolls, if you roll 1 or 3 evens, you win

Best ResponseYou've already chosen the best response.1oops, that doesn't actually matter, when \(n=1\) then a) is still 1/2

Best ResponseYou've already chosen the best response.1n=2 gives 7/10 for a, but d is still 1/2 so.... 5 rolls, what is the probability of odd even rolls

Best ResponseYou've already chosen the best response.1Weird... There is no explanation for a)?
