Ineed with this probability problem.

b. 4.5%

Step-by-step explanation:

"If 18% of the beads in a bag are green, 25% are red, and 40% are purple, what is the probability of choosing a green bead and then a red bead if you replace the bead in between?"

The probability of selecting a green bead is 18%.  Since the bead is replaced, the number of beads remains the same, so the probability of selecting a red bead is 25%.  The probability of selecting both is the product:

P(green AND red) = P(green) × P(red)

P = 0.18 × 0.25

P = 0.045

So the probability is 4.5%.
