When using the NumPy random module, how can you return a random number from 0 to 100?

• random.randint(100)

• random.rand()

• random.rand(100)

When using the NumPy random module, how can you return a Normal Data Distribution with 1000 numbers, concentrated around the number 50, with a standard deviation of 0.2?

• random.normal(size=1000, normal=50, s=0.1)

• random.normal(size=1000, mean=50, deviation=0.2)

• random.normal(size=1000, loc=50, scale=0.2)

When using the NumPy random module, how can you randomly shuffle an array?

arr = np.array([1, 2, 3, 4, 5])

• random.change(arr)

• random.shuffle(arr)

• random.rearrange(arr)

When using the NumPy random module, how can you make sure you always get the same result?

• Use the random.seed() function to set a seed before running the other random functions

• Use the random.static() function to set an answer before running your random functions

• Use the random.change() function to change an answer before running your random functions

When using the NumPy random module, what is the probability of getting the value 6 to occur?
