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? (1 point)
7 over 21 multiplied by 6 over 20 equal to 42 over 420
7 over 21 plus 6 over 20 equal to 266 over 420
7 over 21 multiplied by 7 over 21 equal to 49 over 441
7 over 21 plus 7 over 21 equal to 14 over 21
1 answer
The correct answer is 7 over 21 multiplied by 6 over 20 equal to 42 over 420. This simplifies to 1 over 10, so the probability is 1/10.
