1. A deck of cards has four suits; hearts, diamonds, clubs, and spades. Each suit has an ace, king, queen, jack, and the numbers two through ten. If the deck is well suffled, what is the probability that a king of spades or any club card will be drawn?

2. Say True or False for the folowing questions

a. The probablity of an event refers to the chance or likelihood that an event will occur.

b. A sample space is the set of all possible simple outcomes, respones, or measurements of an experiment.

c. If the probability of a particular event A is 1/3, and if after two trials event A did not occur, event A must occur on the third trial.

d. An a prior   probability can be determined with out observation over a large number of trials.

e. If we have two mutuallly exclusive events, the probability of either one of these events occuring my be determined by summing the probabilities of each of these events.

f. If two events are not mutually exclusive, there is a possibility, that both events may occur at the same time.

g. If P(A) = P(A), then the events A and B are independent.

h. If we have four items --- A, B, C, and D ---- there would be eight diferent pairs of two items.

i. The probability distribution of a variable which has a finite number of values is a disecrete distribution.

Solution

a TRUE b TRUE c FALSE d FALSE e TRUE f TRUE g Cannot say h FALSE i TRUE
