What does RANDOM(1, 6) return in pseudocode?

A random integer between 1 and 6, inclusive.

What is the purpose of the following Python code?

python
import random
c = random.randint(a, b)

To generate a random integer between 'a' and 'b' (inclusive) and assign it to the variable 'c'.

Predict the output:

pseudocode
count ← 0
LOOP 5 TIMES
  roll ← RANDOM(1, 2)
  IF roll = 1
    count ← count + 1
  END IF
END LOOP
DISPLAY count

A number between 0 and 5, inclusive, representing the number of times 1 was rolled.

Complete the following Python code to generate a random number between 10 and 20:

python
import random
number = random.______(10, 20)

randint

What is the output of this code?

python
import random
random.seed(42)
print(random.randint(1, 10))
random.seed(42)
print(random.randint(1, 10))

The same number will be printed twice because the seed is set to the same value before each call to randint().

Identify the error:

python
import random
print(random.randInt(1, 10))

random.randInt should be random.randint. Python is case-sensitive.

Predict the output:

pseudocode
number ← RANDOM(1, 10)
DISPLAY number

A random integer between 1 and 10 (inclusive).

Complete the pseudocode to simulate rolling a die:

pseudocode
roll ← RANDOM(____, ____)

1, 6

What is the output of the following code?

python
import random
numbers = [1, 2, 3, 4, 5]
print(random.choice(numbers))

A random element from the list numbers (i.e., 1, 2, 3, 4, or 5).

What is the output of this code?

python
import random
random.seed(1)
print(random.random())
random.seed(1)
print(random.random())

The same random floating-point number between 0 and 1 will be printed twice.
