Question

Among the following that cannot be a probability is

  1. 10%
  2. 10
  3. 10 to the power of negative 10 end exponent
  4. 1 over 10

hintHint:

The likelihood of an event happening or not in numeric terms is called probability. Probability is always denoted by a number between 0 and 1, 0 representing impossibility of the event happening and 1 representing certainty.

The correct answer is: 10


    TO FIND-
    Which of the given options can not be used to denote probability.
    SOLUTION-
    a. 10%
    10% = 10/100 = 0.1
    b. 10
    c. 10 to the power of negative 10 end exponent
    10-10 = 1/1010 = 0.0000000001
    d. 1 over 10
    1/10 = 0.1
    Since we know that probability is always a number between 0 and 1, the only option that does not satisfy this condition is option b i.e. 10 because it is greater than 1.
    FINAL ANSWER-
    Option 'b' i.e. '10' is the correct answer to the given question.
