Probability y Statistics

1. A manufacturer has five seemingly identical computer terminals ready to beSent. Unbeknownst to him, two of the five are defective. A particular order request two of the terminals and the order is filled by randomly selecting two of the five available.

a) Indicate the sample space for the experiment.

b) Denote with A the event that the order is filled with two non-defective terminals. Indicate the sample points in A.

c) Construct a Venn diagram for the experiment illustrating event A.

d) Assign probabilities to simple events in such a way that information about the experiment is used and the axioms stated are satisfied.

e) Find the probability of event A

2. Professor Veronica identifies that of 40 times she arrives at the first traffic light on her way to work, 5 is green, what is the probability that the next time she will reach the following at that traffic light? Use the empirical approach.

3.What is the probability that today will be Thursday? What is the complementary event of the event "today is Tuesday"?

4. What is the sample space when throwing three coins in the air?
