Bruj life is so hard. like aragahah this boy has me head over heels and all i want is him. god why can’t he open his eyes. anyway since your only concern is "given that they play a sport", only the top row is involved (12 total). Of those, 2 play an instrument. P(I|S) = 2/12, or 1/6.
I believe the answer is 9.
The value of y is 7 and value of NO is 5 i believe and the other ones are correct:)
N=5. All the angles of a triangle equal 180 degrees. So set all of your angles equal to 180. 6n+1+9n-4+108= 180. Combine like terms. 15n-3+108=180. Now subtract 108 and add 3 to the opposite side. 15n=75. Then divide 75 by 15. The answer is five!
