An auto supply store sells steering wheel covers arranged on display such that each of two different colors of steering wheel covers, blue, and purple are consecutive in a repeating pattern. If three consecutively displayed steering wheel covers are purchased, what is the probability that two of the steering wheel covers are purple? Pick:
A) 3/4	B) 2/5	C) 1/4	D) 2/3	E) 1/2
After blue and purple, the next steering wheel cover can be of any given two colours, therefore we have total two possibilites, out of which we need purple i.e. 1 therefore prob is 1/2. Correct answer is 1/2.
