1 2 3 4
1 2 3 4 5
2 3 4 5 6
3 4 5 6 7
4 5 6 7 8
There is 2/16 chance to get 3, and 2/16 chance to get 7. Therefore, there is 4/16 or 1/4 chance to get either a 3 or a 7.
Answer: 1/4

What is the probability of picking white?
The probability of picking white is equal to the number of white objects divided by the total number of objects (both white and non-white), assuming that all of the objects are identical other than color. In Geometry, the probability of landing on a white space is the area of the white space divided by the total area.
How often something happens divided by all outcomes is called?
The probability of whatever it was that happens.
What is the probability of getting a number greater than or equal to 2 when rolling a number cube numbered 1 to 6?
Probability is a ratio written as the number of desired outcomes divided by the number of possible outcomes. On a six-sided number cube, there are 5 chances of getting a number greater than or equal to 2 (2,3,4,5,6) and 6 possible outcomes (1,2,3,4,5,6) so your probability would be 5/6.
A spinner is divided into 10 equal section numbered 1 through 10. If the arrow is spun once what is the probability it will land on a number greater than 6?
There are 4 numbers (7-10) which are greater than 6 → pr(>6) = 4/10 = 2/5

What is the formula in probability?
Probability equals favorable outcomes divided by total number of outcomes.
What is a probability of a certain event?
The probability of an event is the chances it will happen divided by all the possible outcomes.

What do you use to calculate probability?
Probability is the ratio of the count of anticipated outcomes divided by the count of all outcomes.
A spinner is divided into 12 equal selections numbered 1-12 . What is the probability of landing on a section with a number that is less than 5?
5/12 If it's wrong don't mind me, i'm not even in middle school yet i'm just smart
Are sister chromosomes identical?
yes because all they are, are one chromosome divided directly in half in to 2 identical chromosomes. :-)
Frequency approach for probability?
Well, that's not much of a question. Perhaps you are asking: What is the frequency interpretation of probability? This is called the classical interpretation of probability. Given n independent and identical trials with m occurrences of of a particular outcome, then the probability of this outcome, is equal to the limit of m/n as n goes to infinity. If you are asking: How can probabilities be estimated given data, based on frequency approach? A table is constructed, with intervals, and the number of events in each interval is calculated. The number of events divided by the total number of data is the relative frequency and an estimate of probability for the particular interval.
What is a prime number with two identical digits?
11 is the only prime number with identical digits. After 11 all numbers with identical digits can be divided by atleast 11 or 3.
