    You again asked for "odds" which is different than "probability". They are both ways to express likelihood, but they aren't the same.

    Probability is the ratio of favorable outcomes to *total* outcomes.

    There are 2 red jacks (J♥ and J♦) in a deck of 52 cards

    So the *probability* is 2 in 52: 

    2/52 = 1/26

    Odds in favor are expressed as the ratio of favorable outcomes to *unfavorable* outcomes. If there are 2 favorable outcomes, there are 50 unfavorable outcomes.

    So the *odds in favor* are 2 to 50 in favor

    2:50 = 1:25

    Odds against are just reversed as the ratio of unfavorable outcomes to favorable outcomes.

    So the *odds against* are 50 to 2 against

    50:2 = 25:1

    Answer:

    Probability is 1 in 26 --> 1/26

    Odds in favor are 1 to 25 --> 1:25 

    Odds against are 25 to 1 --> 25:1

    It depends how many red jacks and how many cards there are to pick from.
