Problem 1 (5 points) A coin is flipped four times. Assume that each of the sixteen possible outcomes {0000, 1000, 0100, 1100, 0010, 1010, 0110, 1110, 0001, 1001,0101, 1101,0011, 1011, 0111, 1111} are equally likely. What is the conditional probability that all flips are heads, given the following information: (a) the first flip is heads? (b) the last flip is heads? (©) at least one flip is heads? (d) at least two flips are heads? (e) the first flip and...

Each of two parents has the genotype blond/ brown, which consists of the pair of alleles that determine hair color, and each parent contributes one of those alleles to a child. Assume that if the child has at least one blond allele, that color will dominate and the child's hair color will be blond. a. List the different possible outcomes. Assume that these outcomes are equally likely. b. What is the probability that a child of these parents will have...

Among 450 randomly selected drivers in the 20-24 age bracket, 9 were in a car crash in the last year. If a driver in that age bracket is randomly selected, what is the approximate probability that he or she will be in a car crash during the next year? Is it unlikely for a driver in that age bracket to be involved in a car crash during a year? Is the resulting value high enough to be of concern to...

1. be recorded. Define events Eli heads are observed, of the two faces is equally likely to hand face-up. Three balanced coins will be flipped once and the number of heads that land face-up is to 0,1,2,3. Note: "balanced" means each a. List all the outcomes in the Sample Space. b. Calculate the probability of each event, Eo,.., E c. Let A be the event "at least one head is observed". Calculate P(E2A) and P(AIE2)

In a fair "Pick 3" game, the first digit drawn should be a zero
with probability 0.1 because there are ten equally likely outcomes.
A lottery player suspects that the game is unfair. To test his
theory, he records the numbers drawn over two years which
constitute 582 plays.
