Whenever Nicole rents a movie from iTunes, the probability that it will be a comedy is 52%. Of the next seven movies she rents, what is the probability that she rents NO MORE THAN two comedies?

Respuesta :

Answer:

[tex](0.48)^7+(0.52)(0.48)^6+(0.52)^2(0.48)^5[/tex]

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

= [tex]=(0.48)^7+(0.52)(0.48)^6+(0.52)^2(0.48)^5[/tex]
