5.6.2 random numbers quiz
question: 1
which of the following returns a random number between 1 and 10?
randomint(1, 10)
randint(1, 10)
randomizer.int(1, 10)
randomizer.nextint(1, 10)
question: 2
how many possible values can randomizer.nextboolean() return?
0
1
2
3

Explanation:

Question 1

To determine which function returns a random number between 1 and 10, we analyze each option:

• randomInt(1, 10): Not a standard function for generating random integers in typical programming contexts (e.g., in the context of the Randomizer class, this is not the correct syntax).
• randInt(1, 10): Also not the correct syntax for the Randomizer class.
• Randomizer.int(1, 10): Incorrect syntax; the method to get a random integer in the range is nextInt.
• Randomizer.nextInt(1, 10): This is the correct syntax (assuming a programming environment where the Randomizer class has a nextInt method that takes a range from 1 to 10) to generate a random integer between 1 and 10.

The Randomizer.nextBoolean() method returns a boolean value, which can be either true or false. So there are 2 possible values.

Answer:

D. Randomizer.nextInt(1, 10)
