Question 1203517: In a bag are five counters each of a different colour: green, yellow, red, blue, and purple. If one counter is drawn from the bag and replaced and then a second is selected, find the probability that a green counter then a blue counter is selected. That is find p(G,B).

p(any color) is equal to 1/5 on the first draw.
with replacement, it's the same probability on the second draw, or any other succeeding draw.
therefore p(g,b) = 1/5 * 1/5 = 1/25.
