Probability
The probability of a certain event is a number expressing the likelihood that a specific event will occur, expressed as the ratio of the number of actual occurrences to the number of possible occurrences. In mathematics, it is a measure of how often an event will happen and is the basis of statistics.

What is the probability of getting 3 hearts from an ordinary deck of cards?
The answer depends on how many cards are drawn, whether they are drawn at random and whether they are replaced before drawing the next card.
If three cards are drawn, at random and without replacement, the probability that they are hearts is (13/52)*(12/51)*(11*50) = 1716/132600 = 0.0129
Well, if you really mean divisible by 4 then the answer is 100% that is probability 1.00.
On the other hand, if you mean evenly divisible by 4, then in the numbers 1-12 there are 3 numbers evenly divisible by 4 (4, 8, 12) since there are 12 numbers then the probaqbility of a number divisible by 4 is 3/12 = 0.25
What is the probability of drawing a three or a heart from a deck of playing cards?
With a regular deck (2-Ace with ♥,♦,♣, and ♠), the probability of drawing a three is 1 in 13. The probability for a heart is 1 in 4, a.k.a. 25% or 1/4 . The probability for a 3 of hearts is 1 in 52.
Improve:
And to be more specific:
because a heart is 25%, and a three is 4/52 % and the h of hearts is 1/52 getting a 3 OR heart is 25% (heart) + 7.69% (a 3) - 1.923% (3 of hearts can't be counted twice!) = .30767
yes, that deck will lose the cards you sold
What does it mean if the probability of an even number is 0?
If the probability of a event is zero, then the event cannot occur. Therefore, if the probability of an even number is zero, then the probability of an odd number is one.
Total number of fruit in the bag = 9 + 5 + 3 =17
Number of Kiwi = 3
Probability of picking a kiwi out of the bag =3/17
The probability of drawing a king followed by a queen is (4 in 52) times (4 in 51), or 16 in 2652, or 4 in 663, or 0.006033.
No, 12 and 18 are not coprime. Their common factors are 2, 3, and 6.
What is the probability of seeing 50 heads if a coin is tossed 100 times?
There are two sides on a coin.
The odds are 50:100, or 1:2.
Half the time the coin SHOULD land on heads.
If that's the case, then the odds of the visiting team of winning is 1 to 3.
According to Hoyle - how many cards muct be cut in a deck of cards?
According to Hoyle - when you cut, you must take at least 5 cards and at most 47 cards from the top of the deck.
What would be the color vision of children if their mom is colorblind and their dad is normal?
Colorblindness is a recessive, sex-linked trait, and the gene that causes it occurs on the X chromosome. For the mother to be colorblind, she must have two copies of the gene and be homozygous recessive. The father, on the other hand, can not have the gene, because he (as a male) only has one X chromosome. So, if we let Xc represent the recessive gene for colorblindness and Xn represent the normal gene, the the mother is XcXc and the father is XnY.
All of their children will receive the recessive gene from their mother. In the males, this means that they will be colorblind, because the chromosome they get from their father will by the Y chromosome. The daughters, however, will get the Xn gene, which is dominant and will override the gene for colorblindness. Thus, all of the couple's sons will be colorblind, and none of their daughters will be.

Its simple what are disjoint events?
Two events are disjoint if they cannot occur together. In set terms, their intersection is a null set.
The probability that 12 randomly selected people from a group of 12 men and 18 women will all be women is (18 in 30) times (17 in 29) times (16 in 28) times (15 in 27) times (14 in 26) times (13 in 25) times (12 in 24) times (11 in 23) times (10 in 22) times (9 in 21) times (8 in 20) times (7 in 19), which is equal to 8,892,185,702,400 in 2,180,547,008,640,000, which is equal to 68 in 16,675,which is equal to 0.00407796.
How many prime numbers are there in a deck of cards?
There are 48 prime numbers in a deck of cards.
The prime numbers are 2, 3, 5, and 7. There are four suits - that makes 16. The numbers are repeated on the top and bottom of each card - that makes 32. The numbers are repeated in the number of pips on the cards - that makes 48.
