let randomIndex = Math.floor(Math.random()*questions.length);
let randomChoice = Math.floor(Math.random()*questions[randomIndex].choices.length);

function getRandomQuestion(array){
  if(array.length === 0){
    return null;
  }
  return questions[randomIndex].question;
}  



function getRandomComputerChoice(array){
  return array[randomIndex].choices[randomChoice];
}

const answer = questions[randomIndex].answer;
const computerChoice = getRandomComputerChoice(questions);

function getResults(answer,computerChoice){
  if(answer == computerChoice){
    return `The computer's choice is correct!`;
  }else{
    return `The computer's choice is wrong. The correct answer is: ${answer}`;
  }
}

console.log(getRandomQuestion(questions));
console.log(getRandomComputerChoice(questions));
console.log(getResults(answer,computerChoice));

I see a small comprehension mistake, make sure to read again what is given to getResults as argument
