For each experiment, determine whether events A and B are independent or dependent.Experiment Events IndependentDependentA deck contains 10 cards numbered 1 through 10. A card is randomly selected and reinserted into the deck. The deck is shuffled. Then another random selection is made. Event A: The first selection is a 7.Event B: The second selection is a 4.Chau randomly selects a sock from a drawer containing black socks and brown socks, and puts it on. Then another random selection is made from the remaining socks. Event A: The first selection is black.Event B: The second selection is brown.A family has two children. Event A: The older child has red hair.Event B: Both children have red hair.A number cube with sides labeled 1 through 6 is rolled twice. Event A: The first roll is a 6.Event B: The second roll is a 5.A litter of puppies consists of black puppies and white puppies. A puppy is randomly selected and removed from the litter. Then another random selection is made from the remaining puppies. Event A: The first selection is a white puppy.Event B: The second selection is a black puppy.

A bin contains orange, blue, green, and yellow water balloons. You randomly select two balloons to toss. Are events A and B independent or dependent? Event A: You choose a green balloon first.Event B: You choose a yellow balloon second.

You roll two number cubes.Let event A = You roll an even number on the first cube.Let event B = You roll a 6 on the second cube.Are the events independent or dependent? Why?A.Independent, because the outcome of the first roll doesn't affect the outcome of the second roll.B.Dependent, because 6 is an even number.C.Independent, because they have no outcomes in common.D.Dependent, because both cubes have six sides.

A card is drawn from a pack of 52 cards. It is then replaced to the pack of cards and a card is drawn from the pack again.Event E is the event that the first card drawn is a diamond.Event F is the event that the second card drawn is a diamond.Event G is the event that the first card drawn is red.Which of the following is/ are TRUE?I. E and F are two independent events.II. F and G are two independent events.III. E and G are mutually exclusive events.

Two fair coins are tossed. Let A be the event that the first coin displays a heads, and let B be theeven that both coins display the same outcome.(a) Are events A and B mutually exclusive?(b) Are events A and B independent?2) A card is drawn from a standard deck of 52 cards. Let A be the event that an ace is drawn and let Bbe the event that a spade is drawn.(a) Are these events mutually exclusive or non-mutually exclusive? Explain your answer.(b) Calculate the probability of event A or event B occurring (drawing an ace or a space).A dice is tossed after a card is drawn. Let C be the event that an even number is shown on the dice.(c) Are events A and C independent or non-independent?(d) Calculate the probability of events A and C occurring (drawing an ace and rolling aneven number).3) Given that
 ∪  = 0.7 and
 = 0.2, find
 and
 ∩  if:(a) A and B are mutually exclusive(b) A and B are independent4) Two dice are rolled and the sum is recorded.(a) List all possible outcomes (i.e. the sample space).(b) Calculate the probability of rolling:(i) A sum of 5(ii) A sum of 4 or less(iii) A sum of at most 11(iv) A sum that is a multiple of 3 or a multiple of 4.5) 200 people attended a blood bank and their blood types are recorded as follows: 50 have type A,65 have type B, 70 have type O and 15 have type AB.(a) Calculate the relative probability of each blood type.(b) If two people are selected without replacement, what is the probability that:(i) One person is type A and the other is type B.(ii) They both have type B blood.(iii) They both have the same type blood.6) A coin is tossed three times and the results are recorded. What is the probability of getting:(a) Three heads.(b) At least two heads.(c) At most one tail.STAT6010 27) Two unfair coins are tossed with the probability of a tail equal to 0.25. Calculate the probability ofgetting:(a) No heads.(b) Exactly one head.(c) At least one head.8) An urn contains 6 black balls, 4 white balls and 5 red balls. The balls are removed 1 at a time fromthe urn and not replaced. If 3 balls are removed, what is the probability that:(a) All three are red.(b) Two are black and one is white(c) All are the same colour(d) At least 1 is white9) 70% of houses in a residential area have an alarm. It is found that 35% of the owners of thealarmed houses have a dog and 42% of the owners of the non-alarmed houses have a dog.a) Construct a tree diagram to show all possible events and probabilities.b) A house is selected at random. Calculate the probability that the house does nothave a dog.c) If a randomly selected house is one of the houses that does not have a dog, what isthe probability that the house has an alarm?10) On any given day, the probability that an employee will drive to work is 0.5, the probabilitythat he/she will cycle to work is 0.3 and the probability that he/she will walk to work is 0.2.If he/she drives, the probability that he/she will arrive on time is 0.6 If he/she cycles, theprobability that he/she will arrive on time is 0.8. If he/she walks, the probability thathe/she will arrive on time is 0.9.
