AP Stats 5.1

The probability that an event does NOT occur is

• highly unlikely

• 1 - the probability that it does occur

• a matter of opinion

• always less than the probability that it does occur

If two events are mutually exclusive, the probability that they both occur is

• 1

• 0

• 0.5

• impossible to determine

Which of the following represents the shaded region?

• A union B

• A intersect B

• A ⊂ B

• B ⊂ A

What statement does the shaded region represent

• or B

• Not A

• and B

• Not B

An assignment of probability must obey which of the following?

• The probability of any event must be a number between 0 and 1, inclusive.

• The sum of all the probabilities of all outcomes in the sample space must be exactly 1.

• The probability of an event is the sum of the outcomes in the sample space which make up the event.

• All of these reasons

Probability is:

• the odds of success

• the outcome of a chance event

• the chance of winning in the short run

• the long-run relative frequency of a chance outcome

The Law of Large Numbers says

• observed probability will approach theoretical probability

• outcomes from repeated chance events multiply

• chance events even out in the long run

• probability will grow without bound

A number between 0 and 1 is:

• an improper fraction

• the probability that a random event will occur

• the calories in a Whopper

• the square root of 2

About 7% of men in the United States have some form of red-green color blindness.  Suppose we want to simulate randomly selecting 4 U.S. adult males to determine the probability that at least one is red-green color-blind.  Which of these are correct assignments of digits for this simulation?  

• 0-7 = color-blind, 8-9 = not color-blind

• 1-6 = color-blind, 7-10 = not color-blind

• 01-07 = color-blind, 08-99&00 = not color-blind 

• 00-10 = color-blind, 11-99 = not color-blind

What is the probability of spinning red?

• 0

• 5/12

• 1/2

• 3/4
