A group of 5 boys and 2 girls are going to sit together in a row of 7 theater seats. They run into the theater and seat themselves randomly. For each of the following, give your answer correct to six decimal places.

(a) What is the probability they will be seated in alphabetical order from left to right?

(b) What is the probability the boys will be seated together and the girls will be seated together?

687.09 dollars       happy now

step-by-step explanation: 6870

1857 times .63 equals 1169.91 subtract that from 1857 you get 687.09

definitely a. the others have almost all data points on one side of the line.

step-by-step explanation:

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
