d. number = random.randint(0, 1) / 100

---------

6.Assuming the random module has been imported into its default namespce, which of the following could be used to generate a random even integer from 2 through 200?

a. number = random.randrange(2, 200, 2)

b. number = random.randrange (2,202,2)

c.. number = random (1, 100) * 2

d. number = random.randint (2,200,2)
