Question 779022: Using a simulation, What is the probability of getting 3 out of 4 true or false questions correct by guessing.
I did:
TTTF
TTFT
TFTT
FTTT
The. I did 1/2x4 and got 1/16 then divided by the total number of questions and got 1/4 therefore a 25% probability of getting 3/4 questions correct.
Is this how to do simulations?

Need represent ALL the possibilities. Four questions, two choices for each question, so how many possible combinations?
1 question ------------- combinations
2 questions ------------ combinations
3 questions ------------ combinations
4 questions ------------ combinations

How many combinations have three questions answered as TRUE? You identified these combinations, so you should be all set to finish.
