a test consists of true/false questions .to pass the test a student must answer at least 6questions correctly .if a student guesses on each question,what is the probability that the student will pass the test

The probability of answering a truefalse question correctly by just guessing is 1/2 or .5. The probability of getting all the questions correct (in this case, 6) is found by multiplying the probabilities of the individual events.
I'll let you do the calculations. I hope this helps.
