A bag contains five different-colored straws. The colors of the straws are red, blue, green, yellow, and purple. John randomly choose one straw from the bag. Then, without replacing it, he randomly chose another straw. What is the probability that John chose the red straw and then the purple straw? Express your answer as a fraction (a/b)

Kevin has a spinner that has 10 equal sections and 2 sections of each color—red, blue, green, yellow, and purple. kevin spins the spinner 180 times. kevin determines about how many times the spinner will land on red or green, and his work is shown below. -kevin has the formula reversed; it should be the total number of sections over the number of red or green sections. -kevin should have used a 4 in the numerator because there are 2 red sections and 2 green sections. -kevin should multiply by the number of sections in the spinner rather than the total number of spins. -kevin calculated the prediction correctly and did not make any mistakes.
