The probability of five cards being four cards from one suit and one card from another suit is the same as the probability of drawing four cards from one suit multiplied by the probability of drawing one card from another suit, multiplied by 5 (for each of the possible positions this other card can be drawn in). The probability of drawing four cards from one suit is 12/51 x 11/50 x 10/49. The probability of drawing a fifth card from another suit is 39/48. All these numbers multiplied together (and multiplied by 5) come to 0.0429. So the probability of drawing a hand of five cards with four cards from one suit and one card from another is 5.29%
It is 3/13, and the colour of the suit is irrelevant.
There are an equal number of cards for each suit (13 for each), and 52 cards in a deck. Therefore, your odds of selecting one card of any specific suit will always be 13 to 52, or 1 in 4 (a 25% chance).
There are 3 face cards in a suit of 13 cards, so the probability is = 3/13.
There are 12 face cards and three of them are hearts. Therefore, the probability of drawing a face card that is heart is 3/12 = 1/4. The probability of drawing a face card that is not a heart is 1-1/4 = 3/4.
