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.

If A couple has five sons what is the chance that their next baby will be a daughter?
There is no simple answer to the question because children's gender are not independent events: they depend on the parents' ages and their genes. However, if you assume that the events then, the probability of a daughter is approx 0.48
What is the probability that a family will have a boy?
The probability is1 - [Prob(No children) + Prob(1 child, a girl) + Prob(2 children, both girls) + Prob(3 children, all girls) + ...]

Odds of getting a king in a five card poker hand?
There are 4 kings in a deck of 52 cards, so the probability of any one card being a king is 4/52 = 1/13.
The probability of getting at least one king is 1 - (12/13)5, in other words 1 minus the probability of not getting a king 5 times. This comes to 0.3298, or approximately 1 in 3.
If you want the probability of getting exactly 1 king, then the calculation is 5*(1/13)*(12/13)4 = 0.2792, or roughly 7/25.
What is the chance of picking a king or jack from a of 52 playing cards?
There are 4 kings and 4 jacks in a deck of cards, so 8/52 which simplifies to 2/13 or 15.4%
How do you calculate probability values?
This is an extremely general question. Perhaps an example of the type of problem you need help with would be better.
What is the most likely roll in dice?
Assuming you are only rolling one die, then each of the six numbers (1,2,3,4,5,6) has an equal chance (1 sixth) of landing face up.
What is the probability of rolling a sum of a 6 on two dice?
On two fair 6-sided dice: 5 out of 36 = 13.89%. Consider the two dice unique. Maybe one is black with white spots, and the other is white with black spots. There are 36 possible outcomes. You can make a table of the sums, and see that five of the outcomes have a sum of 6. Here they are:
- 1+5, 2+4, 3+3, 4+2, 5+1
15
20/4 = 5
5*3 = 15
What is the probability of drawing 2 cards that are all kings from a deck of cards?
The probability of drawing a king on the first draw is 4/52 = 1/13.
The probability that the next card is one of the 3 remaining kings is 3/51 = 1/17.
The probability of both events is (1/13)*(1/17) = 1/221
On a standard 52 card deck is ace high or low?
The ace is high or low not by deck, but is determined by the game rules, or if not defined there, then it is agreed upon by the players pre-game.
What are the odds of rolling a seven or eleven on a pair of dice?
With two dices, there are 36 ways they can be rolled; of these 36 ways:
- Seven can be made in 6 ways (1+6, 2+5, 3+4, 4+3, 5+2, 6+1)
- Eleven in 2 ways (5+6, 6+5)
Probability of seven or eleven:
p = (6 + 2)/36
= 8/36
= 2/9
What does it mean when your balls are red and saggie?
Red and sagging testicles can indicate a variety of conditions, ranging from minor issues like irritation or inflammation to more serious concerns such as infections, varicoceles, or other medical conditions. If you're experiencing pain, discomfort, or any accompanying symptoms, it's important to consult a healthcare professional for a proper diagnosis and treatment. Changes in color and texture can signal underlying health issues that should not be ignored.
What is the ratio of eaches to rolls?
The ratio of eaches to rolls depends on the specific quantities being compared. For example, if you have 100 eaches and 20 rolls, the ratio would be 100:20, which simplifies to 5:1. To determine the exact ratio, you need to know the number of eaches and rolls in question.
