⫸ There are 5 cards face down on a table with the values 1, 2, 3, 4 and 5
written on them. James says the probability of randomly turning over an
even number is 1/2 because there are two possibilities: even and odd.
Which of the following statements is true?
a. James is incorrect because the probabilities less than 1 are impossible.
b. James is incorrect because the two possibilities of "even" and "odd"
are not equally likely in this situation.. Answer: James is incorrect
because the two possibilities of "even" and "odd" are not equally likely
in this situation.

probability of drawing a green marble?
a. 0.5
b. 16/40
c. 19/40
d. 40%. Answer: 0.5
