A home security system is designed to have a 99% reliability rate. Suppose that nine homes equipped with this system experience an attempted burglary. Find the probability that eight or fewer alarms are triggered.

0.0865

Step-by-step explanation:

Binomial Problem with n = 9 and p(triggered) = 0.99

And the photo below is the full answer,

I could not insert the fomula and hope it will find you well.

it would be 6xy and -16xy.

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
