In mathematics, probability can be defined as the likelihood of an event to occur. It can also be called possibility.
Probability of an event must be between 0 to 1.
Therefore, the select any number that can't be an answer to a probability question, the number must be between 0 to 1.
• Any negative number cannot be a probability
,
• Any number less greater than 1 cannot be a probability
Thus, we have:
• 0 ==> ,Yes,, this number can be the answer to a probability question
• 0.5 ==> ,Yes, ,this number can be the answer to a probability question.
• 17/16 ==> ,No, ,this number can't be the answer to a probability question because it is an improper fraction and it is greater than 1.
• 13/15 ==> ,Yes, ,this number can be the answer to a probability question because it is a proper fraction and it is between 0 and 1
• -0.2 ==> ,No, ,this number cannot be the answer to a probability question because it is a negative number.
• 6.9%==>0.069: ,Yes, ,this number can be the answer to a probability question
• 1 ==> ,Yes, ,this number can be the answer to a probability question.
• 109% ==> 1.09: ,No,, this number can't be the answer to a probability question.
ANSWER:
• 17/16
• -0.2
• 109%
