Question 1178961: (a) Suppose you painted one side of a coin white (W) and the other side Black (B). Consider the experiment of
three tosses of that coin and observing the color.
I. Define the sample space for this experiment.
II. Consider the event E= observing at least one white. What are the outcomes under E?
III. What is the probability of observing black (B) at most once in three tosses?
IV. What is the probability of observing exactly two whites (W) in three tosses?
(b) A contractor has submitted bids for two state construction projects. The probability of winning each
contract is .35, and it is the same for both contracts.
I. What is the probability that he will win both contracts?
II. What is the probability that he will win neither contract?
III. What is the probability that he will win exactly one contract?
IV. What assumption did you make in calculating the probabilities?
