brainbuster!!!!!!! =DDD(long riddle)?

[yuffie]

there are 2 cards in front of you
one card has a jack on both sides
the other card has a jack on one side and an ace on the other side
someone takes those 2 cards and shake it up in a bag
you get to pick any of those two cards
but every time you pick a card the jack has to face up
is this a 50% chance of winning

 

[Jake T is back!]

yeah because theres only 2 cards. its one or the other!

or, no because 25% its an Ace and 75% chance Jack

or maybe im wrong both times

 

[♥Brandi♥]

No it's a 75% chance.

 

[Dancer♥]

yes???????? i think so
because two of the four are jacks and you don't know which way is up so yea.
