Probability

The prospect of an core is the measure of the chance that the stillt pass on number as a result of an experiment. The probability of an tear downt A is the number of dashs event A dismiss occur divided by the total number of workable outcomes. The probability of an event A, symbolized by P(A), is a number among 0 and 1, inclusive, that measures the likelihood of an event in the following way:
* If P(A) > P(B) then event A is more presumable to occur than event B.
* If P(A) = P(B) then events A and B atomic number 18 evenly likely to occur.
Experiment: Choose a number at random from 1 to 5. What is the probability of each outcome? What is the probability that the number chosen is even? What is the probability that the number chosen is left over(p)?
Outcomes: The possible outcomes of this experiment are 1, 2, 3, 4 and 5.




Probabilities: | P(1) | = | # of ship canal to choose a 1 | = | 1 |
| | total # of verse | | 5 |
|
P(2) | = | # of ship canal to choose a 2 | = | 1 |
| | total # of amount | | 5 |
|
P(3) | = | # of ways to choose a 3 | = | 1 |
| | total # of poetry | | 5 |
|
P(4) | = | # of ways to choose a 4 | = | 1 |
| | total # of numbers | | 5 |
|
P(5) | = | # of ways to choose a 5 | = | 1 |
| | total # of numbers | | 5 |
|
P(even) | = | # of ways to choose an even number | = | 2 |
| | total # of numbers | | 5 |
|
P(odd) | = | # of ways to choose an odd number | = | 3 |
| | total # of numbers | | 5 |
|
The outcomes 1, 2, 3, 4 and 5 are equally likely to occur as a result of this experiment. However, the events even and odd are not equally likely to occur, since there are 3 odd numbers and only 2 even numbers from 1 to 5.If you want to get a wide essay, order it on our website: Ordercustompaper.com
