The probability of you getting the ace of diamonds two days running is 1/20 * 1/20 = 1/400



The odds of you getting the same card on the second day as whatever you pulled out on the first day is 1/20



So if you specify which card it is before you draw at all, odds are 1/400 of getting it twice. Ie 1/20 to get it once then 1/20 to get that same card again



If you don't care what you get the first time and just want it repeated then the odds are 1/20. Ie probability = 1 of getting a card the first time, then 1/20 of getting that same card the second draw
