A bag contains 16 socks. One sock is chosen at random. The probability of selecting a black, white, or gray sock is 1. The probability of selecting a white sock is 3 4 . Selecting a gray sock is less likely than selecting a black sock. Which statements describe the situation? Choose all the correct answers.

On your first pick, the chance of picking a white sock is  711  (there are  11  socks in total). On the next selection, the chance of picking white is  610  ( 1  white sock has been removed). So the chance of  2  whites is  711×610  which is  42110

Similarly, the chance of picking two blacks is  411×310  which is  12/110

The chance of picking two equal socks is the sum of these probabilities, that is:  54/110

This simplifies to  27/55
