A bag contains marbles of four different colors: green, orange, purple, and black. You randomly pick a marble, note its color, return it to the bag, and repeat this process 80 times. Based on your results, you observe: There are about twice as many green marbles as orange marbles. The probability of picking a black marble is about 1/5. Which of the following could be the data from your experiment? Options: Green 32, Orange 16, Purple 12, Black 20; Green 20, Orange 40, Purple 10, Black 10; Green 24, Orange 12, Purple 24, Black 20; Green 10, Orange 20, Purple 30, Black 20

A bag contains marbles of four colors: black, red, yellow, and blue. You randomly select a marble, record its color, return it, and repeat this 120 times. From your experiment, you notice: There are about equal numbers of black and yellow marbles. The probability of drawing a red marble is about 1/3. Which of the following could be your recorded data? Options: Black 25, Red 25, Yellow 25, Blue 45; Black 20, Red 60, Yellow 20, Blue 20; Black 30, Red 40, Yellow 30, Blue 20; Black 40, Red 30, Yellow 40, Blue 10
