Answer:
Therefore the probability that the card is not brown is
.
Step-by-step explanation:
Probability: Probability is the ratio of the favorable outcome to the total outcome.

Given that, a box contains 2 cards blue in color , 4 cards brown in color and 6 cards yellow in color.
Total number of cards= (2+4+6)=12
∴P(getting a brown card)



∴P(not getting a brown card)
=1 - P(getting a brown card)


Therefore the probability that the card is not brown is
.
See, pls, offered explanation:
1) the both equations are linear function, it means system made up of the both equation has the only solution.
2) if to prove this:

Answer: one solution.
Y ≤ 1/4 x + 3
⇒ region C and D
y ≥ -x + 5
⇒ region B and C
Overlapping region = C
