Ответ:
From those ten socks there are 4 white and 4 black. A total of 8 white and black socks
We are looking for the probability of selecting a white or black sock out of total socks
So the numbe of white and black socks are 8, and the total is 10
So there is a 8/10 chance to select a white or black sock (This would simplify to 4/5)
So your answer is D
