Can a probability be -0.0001?
No. All probabilities lie between 0 and 1 inclusive; -0.0001 is not in that range.
What is the number between 250 and 330?
This is expressed as 250< n < 330 and covers any number in the range 251 to 329. If 250 and 330 are to be included in the range then the expression is written 250 ≤ n ≤ 330.
What are some characteristics of probability?
It is a real number. It cannot be negative. The sum of the probabilities of all possible outcomes of a discrete variable is 1. Similarly, the integral of the probabilities over the whole range of possible outcomes of a continuous variable is 1.
The difference between a number and seven is less than or equal to -3?
This problem can be expressed as, x - 7 ≤ -3. Adding 7 to both sides gives, x ≤ 4. Then the number can have any value in the range 4 to -∞ (negative infinity).
What is the probability ratio?
Probability is a measure of the likelihood of a given event and is a number in the range [0, 1]. That value, if expressed as a ratio, is a probability ratio. It can also be expressed as a percentage or a decimal fraction.
