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%. Now I believe your answer is 45% or around 30 socks. I hope this helped but please let me know.
i believe the answer is B
but i could always be wrong :(
3/15 reduces to 1/5
1/5 = 0.2....0.2 * 100 = 20%
