Question

The number of chips of different colors in Rick's bag is shown below:
•3 red chips
•11 green chips
•7 yellow chips
Rick takes out a chip from the bag randomly without looking. He replaces the chip and then takes out another chip from the bag. What is the probability that Rick takes out a yellow chip in both draws?

A. 7 over 21 multiplied by 6 over 20 equal to 42 over 420

B. 7 over 21 plus 6 over 20 equal to 266 over 420

C.7 over 21 multiplied by 7 over 21 equal to 49 over 441

D. 7 over 21 plus 7 over 21 equal to 14 over 21

Answer 1

\(\dfrac{yellow}{total}=\dfrac{7}{21}\)

Since he replaces it, the amount stays the same

\(\dfrac{7}{21}*\dfrac{7}{21}=\)

Answer 2

so it's C
