Answer:
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%.
