answer
≈ 0.31 = 31 %
set up equation
the probability of someone from the first group having brown eyes is 
the probability of someone from the second group having brown eyes is 
so the probability of both students having brown eyes is*
values
students with brown eyes in first group = 27
total students in first group = 40
students with brown eyes in second group = 23
total students in second group = 50
plug in values and solve

Answer:
A. 69°
Step-by-step explanation:
Given:
m<FED = 179°
m<NED = 19x - 4
m<FEN = 12x - 3
Required:
m<FEN
Solution:
m<NED + m<FEN = m<FED (angle addition postulate)
19x - 4 + 12x - 3 = 179 (substitution)
Add like terms
31x - 7 = 179
31x - 7 + 7 = 179 + 7
31x = 186
31x/31 = 186/31
x = 6
✔️m<FEN = 12x - 3
Plug in the value of x
m<FEN = 12(6) - 3 = 72 - 3
m<FEN = 69°
