Determine the probability of selecting a brown ball
This is calculated as thus:

Substitute values for Brown and Total

The answer can be in fraction or solved further as;

1). is the correct answer.
Y = 8x + 12
if x = -6
y = 8(-6) + 12
y = -48 + 12
y = - 36
if y = 13
13 = 8x + 12
13-12 = 8x
8x = 1
x = ¹/₈ ≈ 0.125
