David as a drawer containing 3 black socks 4 blue socks and 2 brown socks if David Selects a sock from the drawer at random what is the probability that the sock will be blue or brown

2/3

Step-by-step explanation:

Black = 3

Blue=4

Brown=2

Total=9

Probability of blue = number of blue/total number

=4/9

Probability of brown=number of brownies/total number

=2/9

Probability of the sock to be blue or brown=Probability of blue + probability of brown

=4/9+2/9

=4+2/9

=6/9

=2/3
