Question

The incomplete table above summarizes the number of left-handed students and right-handed students by gender for the eighth grade students at Keisel Middle School. There are 5 times as many right-handed female students as there are left-handed female students, and there are 9 times as many right-handed male students as there are left-handed male students. if there is a total of 18 left-handed students and 122 right-handed students in the school, which of the following is closest to the probability that a right-handed student selected at random is female? (Note: Assume that none of the eighth-grade students are both right-handed and left-handed.)

A) 0.410
B) 0.357
C) 0.333
D) 0.250

Answer 1

Don't forget the screenshotttt

Answer 2

oh yeah

Answer 3

x + y = 18

5x + 9y = 122

Answer 4

Doing that you get x = 10 and y = 8. Therefore 5*10 = 50 ofc, Of the 122 right handed students which are female. Thus, the expatiations that a right handed student selected at random at female is 50/122..The rest you can do I'm sure of it, Round to the nearest thousandth

Answer 5

0.410
