There are two coins, one with probability p1 of getting Heads and the other with probabilityp2 of getting heads. One of the coins is randomly chosen (with equal probabilities for thetwo coins). It is then flipped n ≥ 2 times. Let X be the number of times it lands Heads.(a) Find the PMF of X. Your answer should be a formula involving n, k, p1,and p2. (Hint: Law of Total Probability.)(b) What is the distribution of X if p1 = p2?

By rewnting the formula for the multiplication rule, you can write a formula for finding P(A and B) P(A) conditional probabilities. The conditional probability of event B occurring, given that event A has occurred, is P(B A)= Use the information below to find the probability that a flight departed on time given that it arrives on time. The probability that an airplane flight departs on time is 0.91. The probability that a flight arrives on time is 0.89. The probability that a flight departs and arrives on time is 0.82. The probability that a flight departed on time given that it arrives on time is. (Round to the nearest thousandth as needed.) es

You are allowed to take a certain test three times, and your final score will be the maximum of the test scores. Your score in test k, where k = 1, 2, 3, takes one of the values from k to 10 with equal probability 1/(11 − k), independently of the scores in other tests. What is the PMF of the final score?

Chris has just received test results from a patient named Cardi who is infected with a mystery disease. The accuracy of the test is as follows:The probability the test will be positive if Cardi is infected is p, and the probability the test will be positive if Cardi is not infected is q. The proportion of the population that is infected is π. The test comes back positive. Chris has no information about the disease and related symptoms. Suppose Chris does not have a true gasp of the base rates. Chris thinks that the base rate is γπ (gamma*pi), with γ is less than or equal to π. This is to make sure that Chris's belief about the prevalance of the mystery disease is no more than 100%. If p=0.95, 1=0.05, π=1, what must be the value of γ if Chris thinks that the probability Cardi has the disease is 0.9? A. 3.57 B. 0.5 C. 1.05 D. 3.214 Please provide explanation

A large bag contains pretzels with 3 different shapes: heart, square, circle . Billy plans to reach into the bag and draw out one pretzel at a time, stopping only when he has at least one pretzel of each type. Let the random variable X denote the number of pretzels that Billy will draw from the bag. You can assume that there is an infinite number of pretzels in the bag with equal proportions of each shape. Find E(X).
