Probability, P, of 70% or more correct (7 or more correct) is: P(7) + P(8) + P(9) + P(10). See the related link; N=10, P = 0.5, and K = 7, 8, 9, & 10. Therefore the probability is: .11719 + .04395 + .00977 + .00098 = .17189 or approximately 17.2% probability 7 or more correct.

Not sure what a mulitple choice qustion is but if it is anything like a multiple choice question, it is 1/5 or 20%. I strongly advise you to get a dictionary, learn to spell or use a spell checker.

Students are required to answer 2 True of False questions and 1 multiple choice questions with 4 responses If the answers are all guesses what is the probability of getting all 3 questions correct?
The probability of correct true & false question is 1/2 and the probability correct multiple choice (four answer) question is 1/4. We want the probability of correct, correct, and correct. Therefore the probability all 3 questions correct is 1/2 * 1/2 * 1/4 = 1/16.

A multiple choice question has 5 choices if you gets 2 questions what is the probability of getting both correct?
Well they are independent events so it is the probability of getting a correct answer multiplied by the probability of getting a correct answer on the second question. Short Answer: 1/5 times 1/5=1/25
