You own a portfolio that is invested 43 percent in stock a, 16 percent in stock b, and the remainder in stock

docker41 [41]

Multiply the investment fraction by the corresponding return, and add the products. The given fractions add to 59%, so the remainder is 41%. (The total of the fractions is 100%—all of the portfolio.)

... 0.43*9.1% + 0.16*16.7% + 0.41*11.4%

... = 3.913% + 2.672% + 4.674% = 11.259%

charle [14.2K]

Answer:

$(0.48)^7+(0.52)(0.48)^6+(0.52)^2(0.48)^5$

Step-by-step explanation:

Given: the probability that the movie rented by Nicole will be comedy is 52%.

To find: the probability that she rents NO MORE THAN two comedies

Solution:

Probability refers to chances of occurrence of some event.

Probability that the movie rented by Nicole will be comedy = 52% = 0.52

Probability that the movie rented by Nicole will not be comedy = 100% - 52% = 48% = 0.48

Probability that she rents NO MORE THAN two comedies = Probability that she rents no comedy movie + Probability that she rents one comedy movie + Probability that she rents two comedy movies

= $=(0.48)^7+(0.52)(0.48)^6+(0.52)^2(0.48)^5$
