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?

do you know how to find the possibility

luffingsails · Answer

Consider that you are drawing with replacement (very important to note).

So, what you are looking at is (in words):

Probability of drawing red AND
Probability of drawing white AND
Probability of drawing red.

How do you calculate P(A) and P(B)?
