A pet store sells dog collars arranged on display such that each of the four different colors of dog collars, green, red, blue, and purple are consecutive in a repeating pattern. If five consecutively displayed collars are purchased, what is the probability that two of the collars are purple?
Options:
A) 1/4	B) 1/5	C) 1/16	D) 1/32	E) 4/5
After green, red, blue, and purple, the next dog collar can be of any given four colours, therefore we have total four possibilites, out of which we need purple i.e. 1 therefore prob is 1/4.
