Each multiple choice question consisting of 4 choices has just one correct answer. If a student makes random guesses, the probability of getting the correct answer is 0.25. An exam consists of 12 sequentially appearing MCQs. A student coming unprepared to the exam intends to make random choices. a. What is the probability that she gets at least 10 of them correct. b. What is the probability that she needs to attempt 8 question to get the first correct guess c. What is the probability that she has to attempt 10 to get 4 correct answers?

Inside a bag, there are 5 quarters, 2 nickels, and 4 dimes. Two coins are randomly drawn without replacement. Calculate the probability of drawing one quarter and one dime. The tree diagram has been started below.
Draw a diagram to represent all outcomes when: 3 coins are tossed together (XXX or _, _, _ as results on all 3 coins).
There are 3 light switchas in a row and each switch can either be On or Off. Use information to answer parts a and b below. Part A: when considering all possible light switch settings, give the probability of having at least one light switch On. Part B: when considering all possible light switch settings, and using odd notation, give the odd in favor of having exactly one light switch On
Keno is a casino game in which the player has a card with the numbers 1 through 80 on it. The player selects a set of k numbers from the card, where k can range from one to ifteen. The “caller” announces twenty winning numbers, chosen at random from the eighty. The amount won depends on how many of the called numbers match those the player chose. Suppose the player picks ten numbers. What is the probability that among those ten are six winning numbers?
Multiple-choice questions each have five possible answers ( a, b, c, d ), one of which is correct. Assume that you guess the answers to three such questions. a. Use the multiplication rule to find P(CWC), where C denotes a correct answer and W denotes a wrong answer. b. Beginning with CWC ,make a complete list of the different possible arrangements of two correct answers and one wrong answer ,then find the probability for each entry in the list. P(CWC)= P(WCC)= P(CCW)= c. Based on the preceding results, what is the probability of getting exactly two correct answers when three guesses are made?
