Question 354601
Pick a card, any card.
You now know the suit and you now have 51 cards left in the deck.
The odds of the next card being the same suit as the one you already picked is
12 in 51 or {{{12/51}}}
You now have 50 cards left and 11 more in the same suit.
So the odds the next card is in the same suit are 11 in 50 {{{11/50}}}
Keep on like that
Then find the resulting odds. The resulting odds are the product of the odds for each card
{{{(12/51) * (11/50) * (10/49) * (9/48) * (8/47) * (7/46) * (6/45) * (5/44) * (4/43) * (3/42) * (2/41) * (1/40)}}}
Not very good odds
