Correct Answer: BD
When the seed is set using random.seed(1), it ensures that the sequence of random numbers generated will always be the same. Therefore, random.random() will produce the same output whenever it is called with the same seed. As a result, v1 will always be equal to v2 because they are both generated after setting the seed to 1. This makes v1 == v2 always evaluate to True. Additionally, random.choice([1,2,3]) will always select a number from the list [1,2,3], and since the minimum value in this list is 1, random.choice([1,2,3]) >= 1 will also always be True.

May 25, 2022The correct answers are B and D. A is not correct because pseudorandom numbers are always between 0 and 1.

Mar 9, 2022>>> import random >>> random.seed(1) >>> v1=random.random() >>> random.seed(1) >>> v2=random.random() >>> print(v1>=1) False >>> print(v1==v2) True >>> print(len(random.sample([1,2,3],2)) > 2) False >>> print(random.choice([1,2,3]) >=1) True BD is the answer

Apr 11, 2023It's A and D. random.seed (1) generates always the same secuence of random numbers. random.random() withouth setting the seed value always generates a different number everytime you run the program.
