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 .
