    A box has 8 beads of the same size, but all are different colors. Tamy draws a bead randomly from the box, notes its color, and then puts the bead back in the box. She repeats this 3 times. What is the probability that Tamy would pick a red bead on the first draw, then a white bead, and finally a red bead again?

    okay, if you want to find the probability of a compound event, multiply each independent event in the problem

    so in the problem you have, the probability of picking a red bead was 1/8, a yellow bead 1/8, and the red marble probability was used again(1/8), so you would multiply these probabilities to get your answer
