Suppose a drawer contains five brown socks, seven blue socks, and four red socks. We draw one sock from the drawer and it is equally likely that any one of the socks is drawn.

Find the probability that the sock is brown or red. (Type an integer or a simplified fraction.) c. Find the probability that the sock is black. (Type an integer or a simplified fraction.) d. Find the probability that the sock is not brown. (Type an integer or a simplified fraction.) e. We reach into the drawer without looking to pull out four socks. What is the probability that we get at least two socks of the same color? (Type an integer or a simplified fraction.) > of 2
