Each contestant will answer 50 questions: 20 in Mathematics, 10 in current events, 15 inScience, and 5 is Social sciences. The quiz master will draw each question randomly. Find the probability that thefirst question will be drawn is abouta. Mathematics:b. Science of Current Events:c. Social Sciences or Mathematics or Current Events:d. Science or Mathematics:e. Neither Science nor Social Sciences:

A quiz consists of 10 multiple-choice questions, each with 4 possible answers, only one of which is correct. A student who does not attend lectures on a regular basis has no clue what the answers are, and therefore uses an independent random guess to answer each of the 10 questions. What is the probability that the student gets at least one question right?Let's decide on some notations.Let L be the event that the student gets at least one of the questions right.We'll use R for getting a question right and W for getting it wrong (W is essentially "not R").Given the "tactic" of the student, what is P(R) and P(W)?

Question 1125% of all students find this BS examdifficult. You select four random students. What is the probability thatexactly two of them find this exam difficult?1 point0.020.060.210.07

Question 2In a group of students 25% are enrolled in physics, 23% in sociology, 17% in chemistry, 14% in political science, 12% in anthropology, and 9% in math. You are going to select an individual from the group of students. The probability of event A is equivalent to the probability that you select someone who studies social science (sociology, political science and anthropology) or physics. What is the probability of the event A’s complement?1 point0.510.260.490.74
