So what we have then is by factorial Divided by two factorial, 3 factorial ways arranging C c w w w. What could happen is you can have correct correct wrong, wrong, wrong and any order. And that we can do more than one way obviously And it will be 5 C2 different ways basically. The Trickier PF 2.25 squared to correct.75 Cubed for three. The correct point could be 1st, 2nd, 3rd, 4th or fifth Here. Now, one correct only will be point 25 Power 1, 1 correct.

So this will be P of zero plus 1 class ps two and pf zero 10 points 2373. 75 power of five is 0.2373 To four Decimal Places. So on the calculator have those up but I would get zero points 01 5 6, 25. So and this answer that I need It will be 0.01464, eight plus number up here. I'm gonna work out 0.25 power of four times 0.75 times five. So you have five chances to get Exactly four correct. Power one but the one wrong could be 1st 2nd 3rd 4th or fifth.

So Let's do PDF four 9.25 Power four heading for correct one wrong is. So I had this number here To challenge of getting four correct. Not too important but that part B At least four correct. Ok part B Let's actually put this is nine 76 five here. So power five So correct and correct and correct and so on. Mhm 1.25 Each time and I want all five to be correct. So p of being correct then he was one chance out of four. Okay we have five questions here in the exam And the person guesses each one. What is tne probability that she wlll get no more than two questions correct? (Round t0 four decrnal places &5 needed )Įntor your answer In each of the answer boxos. What Is the probability thal she will get at least four questions correct? (Round to four decimal places as needed ) What is the probability that she will get no questions correct? (Round t0 four decimal places as needed ) What is the probability that she will get five questions correct? (Round to four decimal places as needed ) The marking on the ball will determine her answer t0 the question There are five multiple-choice questions on the exam. Assuming that she has no knowledge of the correct answers to any of the questions, she has decided on strategy in which she will place four balls (marked A, B, C and D) into box: She randomly selects one ball for each question and replaces the ball in the box.
