Darren has the option of investing in either stock a or stock b. the probability of the return of stock a being 25% is 0.45, 14% is 0.25, and 4% is 0.30. the probability of the return of stock b being 30% is 0.30, 9% is 0.25, and 2% is 0.30. given the probability distributions for the two investments, what is the expected rate of return for stock a and stock b?
a. 13.65%; 12.85%
b. 17.82%; 11.95%
c. 15.95%; 11.85%
d. 16.80%; 11.45%
e. 14.75%; 13.75%

C)A is 15.95% ,B is 11.85%

Step-by-step explanation:

We know that the expected value in probability distribution is given as

Lets X is the expected value then

For stock A

X=0.25 x 0.45+0.14 x 0.25+0.04 x 0.3

X=0.1595

So the expected return for A is 15.95%

For stock 9

X=0.3 x 0.3+0.09 x 0.25+0.02 x 0.3

X=0.1185

So the expected return for B is 11.85%

So our option C will be the answer of that problem.

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
