The answer is C. This is because there are 4 possible styles times 5 possible colors which equals 20 pairs. To find the probability you take the black color with each one of the style options, this means you have 4 black options. Next you make it into a ratio. 4 options/20 available so the ratio is 4/20 which is reduced to 1/5.
