Question
1)
Consider the following sample space, S, and several events defined on it. S = {Albert, Betty, Abel, Jack, Patty, Meagan}, and the events are: F = {Betty, Patty, Meagan}, H = {Abel, Meagan}, and P = {Betty, Abel}. The complement of F is ___________.
{Albert, Betty, Jack, Patty}
{Betty, Patty, Meagan}
{Albert, Abel, Jack}
{Betty, Abel}
{Meagan}
2)
A(n) _____ distribution can be a useful tool for evaluating risk.
probability
collectively exhaustive
complementary
likelihood
outcome
3)
A(n) _____ distribution is a statistical model that shows the possible outcomes of a particular event or course of action as well as the statistical likelihood of each event.
probability
collectively exhaustive
complementary
likelihood
outcome
4)
f X and Y are mutually exclusive events, then if X occurs _______.
Y must also occur
Y cannot occur
X and Y are independent
X and Y are complements
A and Y are collectively exhaustive
a){Albert, Betty, Jack, Patty}
b){Betty, Patty, Meagan}
c){Albert, Abel, Jack}
d){Betty, Abel}
e){Meagan}
Explanation / Answer
The complement of F is ___________.{Albert, Abel, Jack} hence C. All the events in sample space that are not present in F
b)
A(n) _____ distribution can be a useful tool for evaluating risk. Probability distribution can tell us the distribution of the risk of the portfolio
c)
A(n) _____ distribution is a statistical model that shows the possible outcomes of a particular event or course of action as well as the statistical likelihood of each event. Outcome distribution tells us the probability of each outcome along with the outcome .
4)
Y cannot occur . When 2 events are mutually exclusive then if 1 occurs the other cant occur. so if X occurs, Y cant occur
