Therefore we are selecting
between two options A and B with individual probability (1/2) as
intended.
Problem 5. We wish to select between two options A, B with probability each. We are...
Problem 8. 20 pts] I have a special coin with "memory" that I will be tossing ezactly once every day for the next 4 days (so tomorrow will be day 1). Let p, denote the probability that the coin shows up heads when it's tossed on day i (this means it shows up tails with probability 1 -pi when tossed on day i). Did I mention the coin has "memory"? By that I mean that: 1. On day 1, the...
Problem(13) (10 points) An unfair coin is tossed, and it is assumed that the chance of getting a head, H. is (Thus the chance of setting tail, T. is.) Consider a random experiment of throwing the coin 5 times. Let S denote the sample space (a) (2 point) Describe the elements in S. (b) (2 point) Let X be the random variable that corresponds to the number of the heads coming up in the four times of tons. What are...
Problem 6 In this problem, we will use the Independence Axiom to help Jack make investment decisions. A fair coin will be flipped twice. There are two companies Jack can invest in. A share in the first company pays $100 if the first toss comes up heads and $0 if it comes up tails. A share in the second company pays $100 if the second toss comes up heads and $0 otherwise Jack has to choose between two portfolios. The...
Suppose we have two coins, coin A and coin B, and flip them each 10 times. Let E be the event that every time coin A comes up heads, so does coin B. Find P(E). HINT: Use Conditional Probability

We have a coin with an unknown probability of showing head. We denote this unknown probability by X X and we know that the pdf of X X is given by f X (p)= p α−1 (1−p) β−1 B(α,β) , fX(p)=pα-1(1-p)β-1B(α,β), where B(α,β)= Γ(α)Γ(β) Γ(α+β) B(α,β)=Γ(α)Γ(β)Γ(α+β) , and Γ(n)=(n−1)! Γ(n)=(n-1)! if n n is a positive integer. We toss the coin 5 5 times. Let α=2 α=2 and β=2 β=2 . What is the probability that we observe 4 4...
3 Suppose that a box contains five coins, and that for each coin there is a different probability that a head will be obtained when the coin is tossed. Let pi denote the probability of a head when the ith coin is tossed, where i 1,2,3, 4,5]. Suppose that a (8 marks) Suppose that one coin is selected at random from the the probability that the ith coin was selected? Note that i b (8 marks) If the same coin...
A coin that lands on heads with probability p is placed on the ground, showing heads, at timet 0. Thereafter, randomly but with a rate of λ times per hour, the coin is picked up and flipped. (a) What is the probability that the coin shows heads at any time t? (b) Suppose that instead of flipping it, we pick the coin up and turn it over. What is the probability that the coin shows heads at any time t?...
The next three questions (5 to 8) refer to the following: An unfair coin is tossed three times. For each toss, the probability that the coin comes up heads is 0.6 and the probability that the coin comes up tails is 0.4. If we let X be the number of coin tosses that come up heads, observe that the possible values of X are 0, 1, 2, and 3. Find the probability distribution of X. Hint: the problem can be...
Ex 4 Independence of Two Events
4. Exercise: Independence of two events -I A Bookmark this page Exercise: Independence of two events - I 1 point possible (graded) We have a peculiar coin. When tossed twice, the first toss results in Heads with probability 1/2. However, the second toss always yields the same result as the first toss. Thus, the only possible outcomes for a sequence of 2 tosses are HH and TT, and both have equal probabilities. Are the...
