Question

Once again, the electricity went out in my house just as I was pulling socks out of the dryer. So the lights were out. I had only six single socks in there, a mix of red and blue. If i only pull out two socks, the chances i pull out a red pair I 2/3. What are the chances I draw a blue pair? Show your work.

Answer 1

Answer

probability of pulling out a red pair is 2/3, this means that there are 3 pairs in total out of which there are 2 red pairs.

We know that the total probability is always 1

So, we can write it as

Probability of pulling out one blue pair = 1- Probability of pulling out a red pair

this implies

= 1 - 2/3

= 1/3

Therefore, the probability of pulling out a blue pair is 1/3
