An oil refinery is located 1 km north of the north bank of a straight river that is 3 km wide. A pipeline is to be constructed from the refinery to storage tanks located on the south bank of the river 9 km east of the refinery. The cost of laying pipe is $400,000 per km over land to a point P on the north bank and $800,000 per km under the river to the tanks. To minimize the cost of the pipeline, how far downriver from the refinery should the point P be located? (Round the answer to two decimal places.)

1. In an experiment, a fair coin (with the two sides H and T) is flipped 4 times in a row (or you can think of it as four different coins flipped at once) . a. Write the sample space for this experiment. b. Write the event that the coin lands Heads up exactly 2 times.
2. Suppose in an experiment we flip a coin and then roll a six‐sided die. a. Write the sample space for this experiment. (Hint: there should be 12 total different outcomes for this experiment.) b. What is the probability that the die shows a number other than “5”? c. What is the probability that the die shows an even number or the coin shows “tails”? d. What is the probability that the die shows an even number and the coin shows “tails”? e. Are the events “the die shows an even number” and “the coin shows ‘tails’” mutually exclusive events?
3. For a certain experiment the probability of an event E is P (E ) = .65 and the probability of an event F is P(F)= .55 . a. Explain why it is impossible for events E and F to be mutually exclusive events.
