You create a table to determine the size of the sample space of an
experiment. What is the size of the sample space equal to?
- correct answer - the size of the sample space is equal to the number
of cells in the table (not counting any labels of the rows or columns).
Universe
- correct answer - the universe is the entire category being considered. It
encompasses both a and b and outcomes that are not in either category.
in our example of bob's shoes and suits, the universe would be bob's
outfits, the ensemble of suits and shoes. These outfits would not include
shirts, ties, or socks! Every cell in the table would be included in the
universe.
"not"
- correct answer - the word "not" before a category is everything outside
that category but within the universe.
Venn diagram
- correct answer - a type of chart that illustrates how distinct sets, topics,
or objects relate to one another. Uses circles to represent events
And - correct answer - only that specific choice
,("a" and "b")
Or - correct answer - the choices and the mixture of the choices
(a), (b), (a,b)
What is the sample space for being born on a day of the week?
- correct answer - the sample space would be
Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, and Sunday
The sum of all probabilities is
- correct answer - 1
All whole fractions reduce to 1
Complement - correct answer - the opposite of an event happening (i.e.
The event not happening)
For example, the complement of flipping heads is flipping tails
Complementary event - correct answer - complementary events are
those that do not have any common outcomes, and the union is the
whole universe
If there are outcomes in the universe that are not in either event, then
the two events are not complementary
The events must be properly defined in order to have complementary
events
, For example, "rolling a die and getting an even number" would not be a
complete instance of complementary events (as this is only one event).
However, "rolling a die and getting an even number" and "rolling the die
and getting an odd number" are complementary events; the events are
clearly defined.
The probability of the complement. - correct answer - p(a) + p(not a) = 1
1 - p(a) = p(not a)
1 - p(not a) = p(a)
1. The complement of an event occurring is the event not occurring. True
or false? - correct answer - true
The opposite of an event happening is the event not occuring.
2. If two events have no common outcomes, they are complementary.
True of false? - correct answer - false
Two events with no common outcomes are complementary only if their
union is the whole universe
5. The sum of all probabilities of individual outcomes in the sample
space must equal 1. True or false? - correct answer - true
The sum of all probabilities of individual outcomes equals 1.
4. Complementary events occur whenever there are two events. True or
false? - correct answer - false
