  1. 12/25


  2. 24 out of 26 chance duh

  3. 1/49

  4. So in the beginning, you have 52 cards.  26 are red and 26 are black.  The chances of drawing either a black or red card is 26/52, which is 50%.  However, you have drawn 2 black cards already, so now you have 26 red cards and 24 black cards, that's 50 cards.  Now all you have to do is figure the probability of drawing another black card, and your chances are 24/50 (reduced is 12/25), or 48%.  Hope that was helpful!

  5. alright

    well the probabilty would be one out of fifty because after you take the two black out of the probabilty there would fifty left.

    This would be labeled as dependent probabilty i think sorry i dont remember excactly but the probabilty answer is correct just what its labeled ha i havent done math in a few months lol!

  6. There are 26 black cards and 26 reds.  Drawing a black card first is 26 chances out of 52 since there 26 black cards.  Drawing a black card second is 25/51, since there are only 25 black cards after drawing a black on the first draw.  The chance of getting a third black is 24/50, since there is only 24 blacks left out of a total 50 card.

  7. since in this problem, getting the card is independent event,

    the prob. of getting next card black is 21/56.  

  8. Half of the cards in a deck are black.  You have 50 cards left, and since you pulled two black cards already, 24 will be black, 26 will be red (a deck has 26 of each).  Your chances of getting a black card next are therefore 24:26, or 12:13.

  9. Okay half are black and half are red. (black 26/52) so subtract 2/52 from that which is 24/52. So the possibility of the third card being black is 24/52.

  10. the deck started off with 52 cards total of which 26 (half the deck) were black.

    Now, you have 50 cards left of which 24 are black.

    The probability of a black card being drawn is 24 out of 50 or 24/50

    =12/25

    =0.48

    =48%chance


  11. 52 cards in a deck 1/2 are black 1/2 are red so 26 each if 2 blacks are out theres 24 black out of the deck that now has 50 cards

    IF U JUST WANT ANSWER READ PART BELOW

    so 48 percent chance of another black card or 24/50 chance or 12 outta 25 cahnce lowest terms happy to help

  12. ok, there are 52 cards to chose from, so the chances of getting a black card is 26/52

    take two black cards away, and the chance of getting another black card is 24/50 or 12/25
