Finger [1]

Answer:

Therefore the probability that the card is not brown is \frac12.

Step-by-step explanation:

Probability: Probability is the ratio of the favorable outcome to the total outcome.

Probability =\frac{\textrm{Favorable outcome}}{\textrm {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)

=\frac{\textrm{No. of brown card}}{\textrm{Total no. of card}}

=\frac{6}{12}

=\frac12

∴P(not getting a brown card)

=1 - P(getting a brown card)

=1-\frac12

=\frac12

Therefore the probability that the card is not brown is \frac12.
