u are taking a multiple choice test for which you have mastered 70% of the material. sume this means that you have a 0.7 chance of knowing the answer to a random test stion, and that if you don't know the answer to a question then you randomly select ong the four answer choices. Finally, assume that this holds for each qurstion, ependent of the others. Let p be the probability of getting a random question correct. If the test has 20 questions, what is the probability that the corrected questions are e than two standard deviations away from the mean value? Compute it using the le. f the test has 10 questions, what is the probability you score 90% or higher? Write n your answer using the binomial pmf directly. Don't use the Table. Ewe randomly select 50 questions, compute the probability that your score is 909 her using the approximation to a normal distributiion.

Suppose that you were challenged by a friend to hit the bull's eye of a circular board with two concentric circles namely the inner and the outer circles. Your probability of hitting a bull's eye from a distance is 0.05, the probability of hitting the outer circle is 0.75, and the probability of hitting the inner circle is 0.15.
