a sock drawer has 2 blue pair, 4 white pair, 4 black pair. what is the probability you can pick out 1 blue,1 white or 1 black. you replace each pair after picking
i think is 3/10 im not for sure
2+4+4=10

Add all of them together like you were doing... 2+4+4=10
Then make fractions of the amount for each colored sock in relation to the total...
Blue Pair Probability: 2/10 simplified... 1/5
WhitePair: 4/10 Simplified... 2/5
And so on... 
i like this 4 black pair 4/10 simplified 2/5
