Question

which of the following can not be probabilities? 1, -0.56, square root of 2, 3/5, 1.23, 0, 5/3, 0.02??

Answer 1

It is important to know that probabilities are defined insed the range [0,1], which means they cannot be outside that set of values.

Hence, -0.56, square root of 2, 1.23, and 5/3 can't be probabilities because they are outside the range of values.
