Question

ch 12* you read in a book on poker that the probability of being dealt two pairs in a five - card poker hand is 1/21. this means that if you deal 21,000 poker hands, exactly 1000 of them will contain two pairs. if you deal 21 poker hands, exactly one of them will contain two pairs. if you deal thousands of poker hands, the fraction of them that contain two pairs will be very close to 1/21. question 6 ch 12 which of the following is a correct interpretation of the statement “the probability that a baby girl is delivered in a certain hospital is 0.50”? a computer simulation of 100 births for that hospital would produce exactly 50 girls and 50 boys. in the next two births at that hospital, there will be exactly one boy and one girl. to make sure that a couple has two girls and two boys at that hospital, they only need to have four children. over a very long period of time, 50% of the babies delivered at the hospital are girls.

Explanation:

Probability is a measure of the likelihood of an event occurring over a large - number of trials. It does not guarantee exact outcomes in a small number of trials. For the poker - hand example, the probability of 1/21 means in the long run, the fraction of hands with two pairs will approach 1/21. For the baby - girl example, a probability of 0.5 means that over a long period of time, 50% of the babies delivered will be girls.

Answer:

For the first question: If you deal thousands of poker hands, the fraction of them that contain two pairs will be very close to 1/21.
For the second question: Over a very long period of time, 50% of the babies delivered at the hospital are girls.
