A coin is tossed three times. An outcome is represented by a string of the sort HTT (meaning a head on the first toss, followed by two tails). The 8 outcomes are listed in the table below. Note that each outcome has the same probability.
For each of the three events in the table, check the outcome(s) that are contained in the event. Then, in the last column, enter the probability of the event.

A number cube is rolled three times. An outcome is represented by a string of the sort OEE (meaning an odd number on the first roll, an even number on the second roll, and an even number on the third roll). The 8 outcomes are listed in the table below. Note that each outcome has the same probability, For each of the three events in the table, check the outcome(s) that are contained in the event.

A coin flip: A fair coin is tossed three times. The outcomes of the three tosses are recorded. Round your answers to four decimal places if necessary. Part 1 out of 3 Assuming the outcomes to be equally likely, find the probability that all three tosses are "Tails." The probability that all three tosses are "Tails" is

A coin is tossed 23 times, and the sequence of heads and tails is the outcome. A statistical test is conducted for the following hypotheses. H,: The coin is a fair coin. H,: The chance of obtaining a head is three time as the chance of obtaining a tail. The critical region for the test is the event “more than k heads”. Here k is a positive integer. If we want the power of the test to be at least...

Problem 4. A fair coin is tossed consecutively 3 times. Find the conditional probability P(A | B), where the events A and B are defined as A-(more heads than tails came upl, B-(1st toss is a head) 1St toss is a head Problem 5. Consider rolling a pair of dice once. What is the probability of getting 7, given that the sum of the faces is an odd number?

Suppose that a coin is tossed three times. We assume that a coin is fair, so that the heads and tails are equally likely. Probability that two heads are obtained in three tosses given that at least one head is obtained in three tosses is ___________ Probability that that one head is obtained in three tosses given that at most one head is obtained in three tosses is ____________ at least one means one or more, at most one means...

An ordinary (fair) coin is tossed 3 times. Outcomes are thus triples of "heads" (h) and "tails" (o) which we write hth, int, etc. For each outcome, let R be the random variable counting the number of tails in each outcome. For example, if the outcome is hu, then r (11)=2. Suppose that the random variable x is defined in terms of r as follows: X-6R-2R2-3. The values of x are thus: Outcome h ht|th ththhhttthhth htt Value of ΧΙ...
