In a standard deck of cards, there are 52 cards. To that number, we will add a second spade suit, which has 13 cards, giving a total of 65 cards.
Among those 65 cards, there are 20 face cards; 16 in a regular deck plus 4 from the extra set.
Thus, we have 45 cards which are not face cards.
Since the probability is an unrelated event, the final probability will be the product of the individual probabilities.
On the first draw, there will be 45 "nonface" cards from 65 cards, so the odds will be 45/65.
On the second draw, there will be 44 cards out of 64, so the odds will be 44/64, and so on.
We will get 45 x 44 x 43 x 42 x 41 x 40 x 39 divided by 65 x 64 x 63 x 62 x 61 x 60 x 59
The result of this division will be 0.0652 or 6.52%. When we divide 1 by 0.0652 we get odd of about 1 in 15
