# 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.

### Is there an actual strategy to winning Rock, Paper, Scissors?

Although technically Rock, Paper, Scissors is considered a game of chance, there are a few patterns to keep in mind that could give you a leg up on your competition.
Men are statistically more likely to throw rock first, whereas women are more likely to start with scissors. Further, if someone wins on a particular throw, they are more likely to start with the same choice in the next round. Similarly, if they lose, they’re likely...

### Explain how to estimate 498 divided by 12?

Let's see. Estimating would start with rounding up 498. 498 will
turn into 500. Next, we round 12. Twelve rounds to 10, so it ends
up to become 500 divided by 10. 500 divided by 10 is 50. So,
estimated, 498 divided by 12 would be somewhere near 50.
(by the way, 498 divided by 12 is actually, non-estimated,
41.5.)

### How many possible outcomes for flipping 2 coins?

Assuming the coins are fair, two-sided coins, and landing on
their sides is not an option, there are four possible outcomes if
you consider coin a having a head and coin b having a tail being a
different instance from coin a being a tail and coin be having a
head. Here they are;
Coin A | Coin B
Heads | Tails
Heads | Heads
Tails....| Heads

###### Asked in Algebra, Probability

### When do we use vector algebra in daily life?

In real life unit vectors are used for directions, e.g east,
north and up. The unit vector specifies the direction. Gyroscopes
maintain a direction and keep things level. Whenever and where ever
location is important, unit vectors are a part of real life.
Whenever directions are important in your real life, then unit
vectors are important. If everything was confined to move along a
straight line, then unit vectors would not be important. If you can
move in a plane, then unit...

### What difference between Statistical Sampling and non-statistical sampling?

Statistical sampling is an objective approach using probability
to make an inference about the population. The method will
determine the sample size and the selection criteria of the sample.
The reliability or confidence level of this type of sampling
relates to the number of times per 100 the sample will represent
the larger population. Non-statistical sampling relies on judgment
to determine the sampling method,the sample size,and the selection
items in the sample.
