Answer:
1024 outcomes
Step-by-step explanation:
Within a particular single question, we can select only 1 correct answer from 2 options. The number of ways of doing this is 2C1 and this is 2
This means for each question, there are only 2 possible outcomes. Now for 10 questions, the total number of possible outcomes would be the outcome of each of the questions multiplied by one another.
That would be (2)^10 which is 1024 outcomes
