Dobby the house elf has dropped all his socks on the floor in the middle of the night. He has 30 red socks,22gold socks and 14 black socks. How many socks would he have to pick up before getting a matching pair?
There is a total of 66 socks on the floor the chance of picking up a red sock is 30 in 66 which is equal to a 45% chance. After picking up one sock the chances of getting another red sock is 29 in 65 which is around 44%. Your answer is 45% or around 30 socks. Please let me know if this helped :)
